Server Error Reports
« on: July 30, 2017, 11:53:21 pm »
Hi All,

This thread is to create a central place for reporting server errors instead of having a multitude of threads for such things.

Please do NOT reply to this thread unless you have been instructed to by an error message.

This is NOT for general forum usage issues, this thread is for server outages, configuration problems, etc.

Please Note: I provide gratuitous server support to Dave as a way to support this great community, as such my support is best effort. Please be patient, I am subscribed to this thread and will be notified of your posts.

If any of the below hold true DO NOT post a report.
  • Check the next post under this one to see if we have announced an expected outage, or that we are working on the current outage.
  • Check the last post to see if someone else has already very recently reported the outage/error, we would like to avoid 'me too' posts as they pull us away from investigating the issue.
  • Sometimes the error can be cached after we have announced a fix for the issue, please ensure you clear your browser cache and reload the suspect page before reporting.
  • Some errors (5xx errors) will generally affect the entire website, if you find a single page is reporting this error, it is very likely the error is cached, please clear your cache.
If none of the above hold true, please post a detailed error report, the more information the better. Things that help are:
  • The time the error occurred as close to the second as possible. To expedite matters please ensure you convert your time to GMT (UTC).
  • The browser you use, chome/firefox/ie... opera
  • The URL of the page you were accessing
  • If it was submitting a form such as the forum search, updating your profile, etc... please let us know what exactly you were doing that triggered the error

As is the same with EE, the more detail about what led up to the issue, the higher the odds are of finding the cause and correcting it.

Current Server Status
« Reply #1 on: July 30, 2017, 11:54:14 pm »
Current Status: OK

29/08/2017: We are performing some changes to how backups are handled which is causing some slowness, please be patient while we get this sorted out.
30/08/2017: The new backup system is in place, but will be running concurrently with the old backup system while it's performance is evaluated.
03/10/2017: The server was restarted to lift some network restrictions that HostGator had in place that were causing issues with the new backup system. Not sure why a restart was required but this is what we were advised.
11/11/2017: We are now on a new backup scheme but are still experiencing the 502 issues, but much less frequently now. There are core dumps from PHP appearing that need to be debugged when I get some time to do so.

EDIT: already my second attempt at making this report. The first just hanged forever, then said error. (Sorry, I should have noted what the error said).

I've just got and seen the new 502 error message. Which instructed me to write a message here.

Over the last day or so, the EEVblog website, although it works fine about 90% of page loads. Seems to take ages to load, perhaps 10% of the time. Especially when making posts or editing.

I have also had problems with other websites, so the problem could be at my end. About 10% of websites are problematic and take ages to load, then just fail or hang forever.

EDIT: More detailed report:

Time was about 5:13 PM 3/8/17 UK time.

The page I was accessing was:
https://www.eevblog.com/forum/unreadreplies/

The web browser I was using: Google Chrome with Adblock Plus.

It said:

Quote
502 - Bad Gateway
We are having server side difficulties and are working to resolve these issues as fast as we can.

If you are able please report this error to this thread. But before posting please read the instructions carefully!

Thank you for your patience,
Dave & gnif

EDIT3:
When a page has an intermediate error message, BEFORE getting to the page. It looks like this:
Quote
This site can’t be reached

www.eevblog.com’s server DNS address could not be found.
Search Google for eevblog forum chat public transport hell people
ERR_NAME_NOT_RESOLVED

Which MAY be an occasional problem at MY end. Sorry. I have had to change (or consider changing) the default DNS server, previously. Because my ISP one, can be problematic.

The 502 is certainly server side and not caused by your client. I have noted a few pages with slow load issues I am still looking into, one of which is loading a profile page. In future please post the time in GMT so I don't have to guess at your timezone and try to figure this out (not one of my strong points).

Blinking forum just apparently ate a post that took me 30 minutes to put together.  :rant:
The display came up with a Cloudfare-EEVblog server page with a red cross on the EEVblog server.
~10am Sydney time.
Chrome

BUT it did post.  :-//
https://www.eevblog.com/forum/testgear/owon-xds3202e-vs-siglent-sds1202x-e/msg1276504/#msg1276504

So false alarm but it did give me a sick feeling.
Back to normal now.

Hi All,

Sorry for the delay in this update, I have setup a new backup system on the server to resolve these issues but it's initial sync has been problematic. Once the intial backup has been completed the old backup will be turned off resolving the recent errors.

For the technical minded:
  • Industry standard backup solutution that provides incremental as well as full backups
  • Databases are hot copied using Percona XtraDB rather then relying on a slow dump from MySQL
  • Backups are perfomed using a pull model to a remote secure server in an undeclosed location
  • Said server is on a private VPN both to protect comms, and to avoid needing to give the server a public IP

It dit it again, and reload didn't help.  Same browser as before. Time 30/08/2017 08:43:47 UTC.   I *ASSUME* you haven't been able to turn the old backup off yet.

Edit after seeing reply by Gnif:   Sorry!  In my defence 08:43:47 UTC is 09:43:47 GMT which is clearly before 10:00 GMT.   If you want us to ignore errors from 09:30 GMT to 10:30 GMT please say so explicitly.
Edit2: Correction after seeing reply by Salbayeng.  Sorry about the brain-fart re: GMT/BST  *NOT* adding a new post because I don't have another error to report.

08:43:47 UTC is 09:43:47 GMT
Both UTC and GMT are the same for most purposes (GMT does not have summer time adjustments, so local time in the UK will be different by an hour in summer).
One adjusts for leap seconds as they occur, the other adjusts for leap seconds at the end of the year.
The UTC time standard is physically located at a naval observatory in the USA.

GPS time is nearly the same, but doesn't correct for leapseconds, it is currently about 20secs away from UTC (however all GPS receivers know the difference and will tell you UTC if asked).

Maybe I'm dense, but that was not at all clear to me.  Why would I think that the fact that you are working on the backup system means I shouldn't report a 502 error?

(Or maybe you could change the 502 error message when you don't want reports.)

Just a little update, we are still working on fixing a known issue (actually, the same issue). I have been away and have not had the opportunity to perform some changes that are required to proceed with the fix. I should be able to free up time in the next few days and work with Dave to schedule some downtime required to put the new system into effect.

~55 seconds ago, from Cambridge, MA. Multiple 50x errors attempting to access https://www.eevblog.com/forum/unreadreplies/ from both a cookied browser window and a new Incognito browser window.

Probably 15-20 seconds of outages/repeated failures, then it worked.
Was directed here, followed directions (or tried to), so posting.

Chrome Version 61.0.3163.100 (Official Build) (64-bit) on MacOS.

Nope, it wasn't. The back button took me to an empty editing window (well, actually a quote but my added text was missing).

Yeah, that works sometimes.  It depends on when/where the error happens.
I have seen it happen both ways.  Although much more often on GearSlutz than here in EEVblog.
Their server (s?)are chronically slow. Sometimes so slow you wonder whether they are even "up".

502 - Bad Gateway

At 14:25 AEDT or 03:25 GMT on 06/11/17 the forum main page dropped out and then returned to normal operation after about a minute or so with the assistance of the refresh button, as this interruption did not correspond with the scheduled regular backup time I thought it was worth a mention.

I thought it wasn't even supposed to happen with a regular scheduled backup anymore.

Correct, there is still a very intermittent fault, each problem we fix exposes another one. I am seeing core dumps from PHP now, I just have not had the time to attach a debugger to one yet and see what is going on.

You might as well try to enable slow log for php-fpm for requests that take lot of time and time out in the end, requests that need more than 10s and see what you get and why

It is enabled, we are not seeing slow requests anymore, its a backend crash.

I've experienced intermittent 502 server errors for the past few weeks, after they've been absent for a while. The most recent ones were just now, about 10-20 minutes ago. They tend to be on all pages, and typically last for about 1-3 minutes.

Thanks guys, I will see if I can trace down the cause. It's great there are getting fewer, it makes it easier to find the trigger in the logs :)

Recieved error 502 while browsing the open source hardware section of the forum. Stayed that way for 3-5 minutes. I tried going to the main website (eevblog.ocm) and was greeted by "Error establishing database connection".

Happened around 5:04pm Eastern

I also had error 502 (lasting for a few minutes) and "error establishing a database connection" on the main site.".

A few minutes ago. It is now 10:07 PM UK time.

At the start of the difficulties, the forum was failing to supply me with pictures. Then a minute or so later, I got the 502 errors. (Probably because I tried to reload the page, because of the missing pictures).

502 - Bad Gateway

At 09:00 AEDT or 22:00 GMT on 23/11/17 the forum main page dropped out and then returned to normal operation after about two minutes or so with the assistance of the refresh button, this interruption appeared to correspond with the scheduled regular backup time but it was mentioned in a recent post that these events should no longer be occurring, I do not know whether events around this time window are to be ignored or informed.

It certainly was, this time it wasn't a server issue as such, it was simply an inrush of hits to the shop to buy meters.

I got error 502, for around 4 to 4.5+ minutes.
It is now 9:52 PM UK time.

(yesterday, at around this time, maybe 10:18 PM ?, I also had error 502 for a couple of minutes or so)

Then a few seconds before it restarted ok, I got this:

I have been getting persistent errors since joining up. I am assuming you have cleaned out the error logs on SMF? It doesn't like being large. So rather than been strictly a server issue it may also be a backend SMF issue contributing to the server load? There is also a few ways to then use the server log to debug any SMF issues.

Also I haven't found a thread related to forum setup ideas and while I understand this forum is bare bones SMF this Mod giving some simple up down navigation buttons is worth adding. I have used it in a couple of forum builds/rebuilds in the past. The Mod author is also good at keeping it updated to current versions too. https://custom.simplemachines.org/mods/index.php?mod=3433

Err 502  again on Dec 28, 2017,  around 21:45 UTC. Was in error for quite some minutes.
Accessing: https://www.eevblog.com/forum/unreadreplies/

(but from the quite often seen errors 502 I get here, I observed it is irrelevant of what browser, device or page. The server just spews E502 from time to time - or maybe quite often.)

There was an incident of server overload, a script was hammering MySQL. I don't have time to look into it right now unfortunately, my office took a lightning strike that fed into an Ethernet cable... lots of dead Ethernet gear and NICs.

Correction The server was under a DDoS attack by a cluster of servers trying to overload the website by flooding posts to the search input. The attack has been blocked.

It seems to go dead for about 5 minutes almost every evening around 21:30 GMT.  Is it a windows server on a daily reboot or is the a backup that runs which takes the site off line?  Not complaining, just curious.

I apologize for the outage that occurred during Dave's Live Stream just now. This server came under heavy DDoS attack from a range of addresses just as Dave started to attempt to perform the draw. This was not an inrush of viewers, I had to block 50 IP addresses, most running at over 100 requests/sec, a few of them over 200/sec, and one at over 1000/sec.

173.167.206.137 was the heavy hitter at 1000/sec.

We are behind CloudFlare which is supposed to block this kind of thing, but it just proxied it all through... what a Joke.

A subset of Comcast.  Probably one of the business accounts.  I'm sure a complaint to Comcast will bring swift results.  ::)

Comcast has been contacted. There is clearly a remote viewer sitting on that IP, looks very old and unmaintained, likely compromised.

Just a notice to everyone

There will be a short database outage in a few minutes so I can change a few settings in preparation of the server move.

This does not mean the new server's are ready, I simply need to make a change so I can keep them in sync during the testing phase.

Edit: Done

No timeout either it looked like the white blank page was the content...

Rebooted the computer and tried again: same thing.

Fine now.

I've been checking out a few things and found one that serves me a blank page...
https://www.eevblog.com/forum/dodgy-technology/
I can get to the latest updated thread in that board, but not to the thread list.

I've checked this 3 or 4 times while browsing the forum - and it has not changed over all that time (about 2 hours, on and off).   https or http makes no difference.

The link to dodgy technology doesn't work for me.

Not that I really want it fixed. I'd never have noticed normally. But in the interests in getting everything sorted asap I can confirm I also get a blank page.

This appears to be the only thing still down, though I haven't tried absolutely everything.

I'll just have to post my rant in General. >:D

When I "show unread posts since last visit" I get 4 pages.  Pages 1-3 are fine but 4 (or hitting "Next" on page 3) serves me an empty page (status 200, 0 bytes) just like the rest of you are describing.  :-//

I haven't noticed that although I tend to click on the numbers in preference to clicking "next". So it appears to be working correctly to me. I'll check tomorrow when the unreads posts have had a chance to accumulate to 4 pages.
I thought I would fool it by going to page 3 of 4 and selecting and marking all the topics read so that the older stuff would move up.  Nope, last page is blank.  And now that I've gone through the 3 pages that I could see and marked them all as read, clicking "show unread posts since last visit" serves me a blank page.  Weird.

Same here.  I've felt that this 'feature' most of the time served up way too much in terms of how far back it went anyhow.  In this case page 5 would take me back past stuff that are easily outside the range of my last visit time.

Interesting that although I get a blank page if I try to access the dodgy-technology forum area,
I can correctly read the thread pointed by the 'Last post' for the same area, as indexed by the main EEVblog forum page

EDIT: and also access the other 'dodgy' threads via the 'previous' and 'next' buttons on the top and bottom right side

Hi gnif
Search tab result problems (didn't try the text box)

Normal search, not Advanced search.
Search for : transformer winding

Scroll through P1
Hit Next or P2 and the page defaults to a Revise Search page, not the next page as one expects.
Similar results with the page menu at either top or bottom of page. Got the 2nd page once only but never a further page.

Chrome browser.

I fixed it, took a few hours of debugging. The seo friendly plugin doesn't support UTF-8 properly and was trying to insert a duplicated record into a table inside an output buffer callback, as such a white page was generated with no errors, nor debug logging of the fault.

The solution was to strip all non ASCII 7-bit character from SEO urls.

Wow, glad somebody understands all this php and SQL stuff.  I run a web store, and have a very rudimentary understanding of it, but just enough to be dangerous.

Thanks for fixing that forum/thread!

For some reason the main site and the forum are extremely slow with waits to close to half a minute to timeouts today. Test with other sites are all OK.
I go through the Toronto hub I think. Will try VPN to US site and see.

Not so much errors gnif but at times the forum is very slow to refresh, accept a post or just general viewing.
Might need a  :-/O somewhere.

There is currently an outage with one of the two servers, looks like a bad route which I am investigating.

Fixed, we are now back at full capacity. One of the servers had been null routed as a bug in SMF4M was being abused to proxy redirects to external websites.
The site became slow because both servers could still see and talk to each other, as such they had no way to determine that one had lost connectivity. Traffic had to timeout before it would be sent to the other server, so no outage, just slow.

Thanks gnif
So that's a win already for the dual server redundancy. Albeit in the weird way made it slower than it otherwise wouldn't have been. But better slow than offline.

Normally with a server outage the up server will see the other server is no longer responding and will take over it's duties, but because the data center had null routed the external traffic, the two servers could not see there was a fault condition. In what would be considered a normal outage there would be no visible performance impact on the hosting.

I couldn't get through at all but when I went to an external site it showed some places getting through and others not.  Seemed to be no rhyme or reason to physical locations worldwide that connected and didn't so I just waited it out.

So in this case, out of curiosity what would have made it act "slower"?

So in this case, out of curiosity what would have made it act "slower"?

We have two IPv4 addresses listed in DNS for this website, both for load balancing and in the event something like what happened here occurs. In normal operation both IP addresses go to a single load balancer which then routes them to one of the two servers. During a fault the faulted server's IP address will be taken over by the still working server, allowing normal operation, but as stated above, this did not occur due to internal communication between servers still being fully functional.

The delay was because of this design, one IP address to the world was offline. Your browser is designed to try to contact each IP address listed in DNS, failure to contact one after a timeout (normally 30 seconds), it will try the next, it was this timeout that was causing the slow behavior. Just like when you try to go to a domain that is offline, there might be 30-60 seconds before the browser gives up.

Something's not right.  :-//
502's off and on for a couple of days and mainly in the evenings AU time, then this just a mo ago when trying to refresh the main forum page:

Connection Problems
Sorry, SMF was unable to connect to the database. This may be caused by the server being busy. Please try again later.

Generally works fine after a couple of minutes and loads just as fast as normal.  :-//

Logs over the last week show now issues with the hosting or slow load times, and my manual spot checks have not turned up any problems.

I find it amusing though, people now really notice if it's slow... when I started helping dave out, it was normal to be slow, and people only complained if it was down.

The short outage that just occurred was due to a connectivity failure at the data center.  EEVBlog and several other clients that host at the same data center were offline for this period. Nothing to be concerned about :)

Hi gnif,

When using Tapatalk, for the last few weeks links to photos hosted on the form are appearing as broken links.
It appears to correspond to this Tapatalk issue: https://www.tapatalk.com/groups/tapatalksupport/photos-problem-t40891.html
Which they eventually think is caused by "We find the domain of your forum registered in Tapatalk is HTTP protocol. But the attachments were uploaded to the HTTPS domain."
We have been https for some time now, so this may be a red herring or has the hosting of attached files been recently changed on the server?

Thanks,
Towger.

Bug report: login never works in the mobile site.

Symptom: when trying to log in in the mobile site, it always fails if the login period is set to forever.

Expected behavior: after putting in the correct login credentials, selecting “keep logged in” on the mobile login page and hitting the login button, the user should be logged in.

Observed behavior: Instead of logging the user in, the error message “The login session has timed out” appears and the user is not logged in.

Platform: iOS 12, iPhone 7 and iPad mini 5th generation.

Note: logging on the desktop site, then switch to the mobile site is a viable workaround, but it doesn’t work very well on small-screen devices like iPhone due to the font size.

Generally not an issue but I was maintaining a hidden dummy forum to try mods and play with layouts before unleashing them on public forums. Might be worth it especially when SMF 2.1 'finally' gets released to try out any current mods and tweaks you have installed prior to upgrading the Forum proper.

Running 'testing' forum of this size and complex configuration is a feat in itself. To accurately test how things will behave the configuration has to be near-identical, cluster configuration and all. That said when the next version is out of RC I plan to perform an install and test how the migration to it goes, I am dreading it however as I know that most (all?) mods/plugins will break.

I am not right up to speed on where 2.1 is heading but the early on MODS not working from 2.0 to 2.1 is still the same by the sounds of it then. I do know a few of the mod devs had already made versions that were running on the Beta but still suspect. Even when it comes out might be worth hanging back to see if there is carnage on other forums first. Testing forum will never be perfect but it did save me when MOD's conflicted occasionally.

Sorry, I didn't see the other post.  I wasn't sure where to post a problem report.  Anyway, the thread in question opens just fine in IE or private Window Firefox, so it just has something to do with my FireFox plug-ins.

It is about page 60: https://www.eevblog.com/forum/testgear/siglent-sds1204x-e-released-for-domestic-markets-in-china/1475/

It doesn't open Chrome, Edge, IE or Firefox.

I think the problem could be that the attachments are named *.PNG but are in fact BMP files?

I found a bug with the 'Insert Code' feature.  Example:

Click just below the link 'select'.
Code: [Select]
module vid_pattern_generator(
input wire pclk,
input wire reset,
input wire pc_ena,      // Pixel clock enable
input wire hde_in, // Horizontal Display Enable - high when in display area (valid drawing area)
input wire vde_in, // Vertical Display Enable - high when in display area (valid drawing area)
input wire hs_in, // horizontal sync
input wire vs_in, // vertical sync


output reg hde_out,
output reg vde_out,
output reg hs_out,
output reg vs_out,

output reg [RGB_hbit:0] r_out,
output reg [RGB_hbit:0] g_out,
output reg [RGB_hbit:0] b_out,

);

parameter RGB_hbit    = 1;  // 1 will make the RGB ports go from 1 to 0, eg [1:0].  I know others prefer a '2' here for 2 bits


always @(posedge clk)
begin
if (reset) // global reset
begin



end
else
begin
if (pc_ena) // once per pixel
begin

// ***************  insert generator code here
// ***************  also remember to pass through the hde,vde,hs_out,vs_out
// ***************  in the future, numerous delay sizes may be needed if you are performing functions which take multiple clocks before a true pixel becomes valid

end
end
end // always @clk
endmodule

Just above, where I said 'Click on this code [select], the text in the code box should have been highlighted, or copied into my windows text clipboard where I should have been able to paste the ASCII text into my own text editor.  However, clicking on the '[select]' does nothing at all.

I'm using Firefox.

I can confirm it doesn't work in Firefox but it works fine in Chrome, Edge and IE. Not sure if this is a server problem or a Firefox one.

I just tried another community software engineering forum who has the same feature, using Firefox, and it works fine.  This forum must be using some special coding which isn't compatible with Firefox.

In Firefox on this forum, going over the code 'select' with my mouse shows a 'javascript:void(0)' at the bottom left of my browser.
On the third party forum, moving my mouse over their code 'select all' shows a valid https link.

Tested in Firefox 70.0.1 (the very latest production version) and it fails. Doesn't in other browsers, as previously noted.

If you fire up the Firefox web console you see the following messages:

Quote
WARNING: cdn.mathjax.org has been retired. Check https://www.mathjax.org/cdn-shutting-down/ for migration tips. MathJax.js:32:13
Loading failed for the <script> with source “https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js”. new:1:1
IndexSizeError: Index or size is negative or greater than the allowed amount 4 new:47
    smfSelectText https://www.eevblog.com/forum/chat/website-error-reports/new/?topicseen#new line 5 > eval:47
    onclick https://www.eevblog.com/forum/chat/website-error-reports/new/?topicseen#new:1


So it looks like it's both Firefox and SMF in combination. Obviously it's the index error that's causing the problem and it's probably related to the failure to load ajax.googleapis.<snip>. Note that I can quite happily load the ajax.googleapis... javascript in a different Firefox window so something about SMF is causing it to fail to load.

That mathjax deprecation warning looks like it needs attending to as well.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

For those reporting bugs/problems with the forum, I am sorry but this thread is for server errors only, not forum bugs.

Apart from last nights outage and Server issues there is another problem that reared it's head yesterday.

Broken thumbnails not linking correctly to the picture that was uploaded. I 'fixed' one post by removing and replacing the files in the TEA thread but I have left this one https://www.eevblog.com/forum/chat/3d-printer-yet/msg3103687/#msg3103687 broken for a look.

The thing in common with the breakage is there is a space in the file name.

The edit and new post screen appears different in the attachment area as of yesterday so was there a new MOD installed yesterday or a different version of one installed? I suspect there is now a conflict with one of the file upload ones installed.

This should be resolved as it was part of last nights efforts and I have regenerated the thumbnail in question.

It has happened here just a little while ago - https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg3104394/#msg3104394

The pic of a small speaker titled 1-Taming the Speaker.jpg now has the thumb from and seems to point to a pic from a later post; mnem-mask.jpg.


And here as well, recently; last time I was on thread this post was correct as well: https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg3103998/#msg3103998

The image bean's Post.png SHOULD be a screencap of a TEA thread post by beanflying; that image now has the thumb from and seems to point to the battery image from the above post.

I usually use Firefox on my PCs; I brought up the thread on my iPad/Firefox and still FUBAR the same way, so not a local cache issue. Same behavior in Edge.
 

This may be related to another bug that has been happening for months; when posting multiple images, IF the posting process is interrupted for a new post warning, the damned thing just forgets the first pic. It attaches the rest of the pics normally, but that first one you ALWAYS have to go back and attach again.

As you can see, most of my pics in that post have spaces in the title; however the only one it barfed up was the first one, which I had re-uploaded because of the other bug. :-//

Let me know when you're done reviewing those posts and if you need I'll go back and re-attach the correct images.

Thanks,

mnem

SMF doesn't care about the filename, it stores all attachments as a hash of the file contents and references them via a table. There are two possible reasons why this happened:

1) The bug you mentioned
2) The maintenance last night was intended to correct some sync issues between the web servers as the database cluster had lost sync. Normally this would be fine, but there were other factors at play at the same time that prevented them from determining who was the "latest" and both were accepting update/insert queries at the same time (split-brain).

I should have been clearer I am sorry, if this is seen on new posts as of today, please let me know. Feel free to fix any that are messed up from prior.

Did something change today with the forum compatibility settings ? All the other sites are fine but I can no longer access the forum from my TV in the bedroom which runs an old crappy version of Chrome 22. I have reset everything my end but still get an Error 113 as shown in the image below. This message was posted from my main PC in the study.

An alternative is FF on a FireTV. I picked up one of the older brick-style ones cheap; it's powerful enough (Quad-core, 2GB RAM, MIMO) even today, and it still supports up to 2K native streaming with all the PrimeVideo (of course) and Netflix-certified HD content working correctly (Widevine DRM, etc) and Amazon still keeps them updated.  :-+

But the big plus is that even if you DON'T root & flash (you would NEVER do that, right...?  >:D), they have the ExpressVPN client available in the Amazon App store. For me, this makes it possible to keep watching my Hulu, etc while "visiting" in the Great White North... your reasons for wanting a VPN would be none of my business.  ;)

So far, these are the borked posts:

https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg3105850/#msg3105850 <-- repeat borkee

https://www.eevblog.com/forum/chat/3d-printer-yet/msg3106050/#msg3106050 <-- newly borked

I went back a few pages before the repeat borkee post and everything there seems to be okay; but there were several posts I fixed before as well so no idea if they'll decide to get in on the fun next time I post a pic. :-//

I have managed to replicate this, it seems to be caused when you try to post the message before the attachment has finished uploading, or you cancel an attachment and then upload another. Still trying to nut down the exact sequence of events that cause it.

That last one was a .heic that I forgot to convert to .jpg . Of course... like we needed to add more confusion.

No, usually the progress bar completes like in half a sec; I may or may not see a thumb right then. Usually if I don't, it's because HEIC or some similar invalid filetype. I HAVE occasionally had it error out with something to the effect of "File too large or took too long to upload", even when I was only uploading a single pic like 1-1.5MB...?

Not in the last couple days, tho.  :-//

However, this post: https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg3107484/#msg3107484

I added a 3rd pic after posting; 14-Manufacturer Info.jpg. It IMMEDIATELY showed up in place of the first pic in that post.

Then, just to see if it would happen again, I made another post. Then cyborg.jpg replaced both instances of that pic.  :-//

I am sorry, I have had limited time of late and have not yet had an opportunity to dig any deeper into this.

There have been other higher priority issues to resolve before looking at this issue, I have spent the last few days working to get backups working after server updates, finally succeeded. Doing a remote incremental backup of the SMF attachment directory consisting of over half a million files (around 60GB) internationally is a nightmare. We are using GlusterFS which limits options with how to do this backup, otherwise, I would just mount an image over the attachment directory and snapshot its backing storage each time. (tar/gz of the directory is not an acceptable option due to server load concerns)

Oh, man... I'm so sorry.  :-[

I didn't mean to make it sound like I was unhappy with your work; I wouldn't have your job for all the money in the world. ;) I would literally rather work HellDesk in a borg cubicle ship again.  :-DD

No, I was grousing about Murphy being a little skank; REFUSING to propagate the fault in here, where it would be easy for you to see.  :P

Carry on, sir. We all know (at least everyone I hang out with) that you're doing the best you can with limited resources.

Oh, and thanks for all the hard work. Don't think we haven't noticed you monitoring the TEA thread at 2am; we grok the dedication therein.  :-+

I tried to post 3 photos, some quoted text and a comment a little while ago.   When I hit "post" I got an "upload files" dialog and when I clicked OK it simply hung.  An attempt to post from another browser tab led to it getting posted missing my comments and 2 of 3 photos.  I had a similar experience about a week ago shortly after which the forum became inaccessible for several hours.

Regarding the mysterious picture adds/replacements. I caught this problem in mid post that might give some clues to what is going on....

I am entering in a new post. I add a picture. In this case it is a picture of a mushroom in a photography focus stacking thread. I do the usual and add the pic, the post has not been sent.

In another window, I then scrolled through my old posts to find one that I intended to link into the post that is still open.

My eye caught that the pic of the mushroom had been substituted for a post of a graph in a corona virus thread - literally added to the post and when viewing the post, I can see that it was added and I could also see a notice:

There are attachments found, which you have attached before but not posted. These attachments are now attached to this post. If you do not want to include them in this post, you can remove them here.

So leaving an unattached photo (as when you are writing but have not submitted a post) is fair game to be inserted into any of ones posts that you view (not modify). Sounds nutty, but it looks like that is what just happened. I will complete the post and edit this message to see if it changes.

EDIT: as you can see, the pic in "limbo" got attached to this post. I did not add it to this post as per normal. Now that I know, I will be sure to have all my pics for a post lined up before opening any other windows or doing any other actions.

EDIT: I also see that the mushroom pic remained added to the corona virus post and bumped the original pic. I had to 'hand' correct that.

EDIT: and further, while the thumbnail pic attached to this post is the mushroom, the pic after the thumbnail is clicked, is the graph from the corona virus thread that I had to replace. I will log off hopefully clear the cache du jour and see if there is persistence....logging off/on makes no difference.

Pics in limbo are evil and get put in places that you don't want. Orphaning pics is the devils work  :)

Because some of the quote tags were in the wrong place, I edited it, is this what you wanted?

Why do you have the 20 MHz BW filter turned on for this? 
[/quote]

Sorry, the [b]AWG[/b] isn't faster :(

[quote]
A 1024 point FFT with a 1 ns sample interval has a 500 MHz Nyquist and 977 kHz RBW.  With a 1024 pixel wide screen *every* sample can be shown. There is no interpolation needed.
[/quote]

Timebase is 20ns/div => ~1000 pixel = 200 ns, plus some headroom for zoom-in after stopping the capture. In the time domain display of the first image (-> step interpolation) you can see that the 1ns samples from the ADC are more than one pixel wide.

I'm pretty confident that the reported 12.5Gs/s FFT sampling rate is indeed the (upsampled) display buffer sampling rate for the selected timebase. Particularly in the first image, the spectrum beyond 1GHz matches the expected spectrum of the step-interpolation as shown in the time-domain trace.
[/quote]
Please put a 50 ohm thru termination on it and repost.  A BNC tee with a 50 ohm terminator is "good enough".  I'll address the rest later.  Interpolation does *not* imply greater BW.  Common knowledge if you resample via Fourier transform as I usually do.

Wow, you are right. The pic displayed (the one you referred to as from a news cast) was the last pic that I attached to a post and it was attached to a post after making the original post in the this thread.

I wonder if my original post in this thread (the mushroom thumbnail but varying pic when you click it) will pic up the last pic link that I use. Testing it with this pic:

[attachimg=1]

Edit: well, so far it (the mushroom thumbnail in my original post in the thread) has NOT picked up the squirrel post above - it still clicks to the newspost pic. Odd.

I've noticed that when attaching 2 or 3 images in-line, full size, the order of the attachments is not always respected...  I then have to edit the post and change the AttachImage tags to make it work...

"I've noticed that when attaching 2 or 3 images in-line, full size, the order of the attachments is not always respected..."

I used to add the attachments in reverse order.
I used to add the attachments in the correct order one by one, "modifying" the post after posting to add attachment 2.

None of them are 100%, it seems worse now where a thumbnail doesn't open the correct image - as well. :horse:

Yep, that's an unrelated problem discovered immediately when the two image attachment plugins were added. There are no plans to fix it. :/

Different people are reporting different things, maybe a database or cache coherency issue?  Seems related to the relatively recent attachment upgrade, but I wonder why it didn't show up as a problem before; if the caches just weren't filled up until recently, that could hint at something?

Not sure... like Gyro's example; I've had a post with a single image bork two older posts daisy-chain style. If I delete the borked pic to replace with the correct one, sometimes THAT pic will bork other older posts further down the thread. I think there's something messed up in how the database handles file pointers, m'self... but that's just drawn from hazy memories of Filesystems Forensics coursework in Uni almost 2 decades ago... :-//

The messages and images may be served straight out of a database...   no file system involved.   It seems like a pretty ugly bug, though, that one message can affect another.  Definitely things are being scrambled somewhere in the system, possibly incompatible libraries after a patch or update, or something like that.

Yeah, that's me misremembering/misusing terminology last grokked over a decade ago.  :palm: gnif stated a couple pages back in the interest of transparency that SMF stores all attachments as a hash of the file contents and references them via a table. To me this sounded like pointers (base address and offset address in a table?) and I probably should've kept my mouth shut.  :-DD

What we are seeing is a fault of that type -  relationship between two logical entities has gone amiss, whether implemented as pointers or references to another table or whatever.  FUBAR covers it!  :D

I've encountered this nasty picture posting bug with my posts in this thread: https://www.eevblog.com/forum/projects/show-us-your-mains-waveform!/msg3128860/#msg3128860 , they should have two pictures each. But only the first uploaded picture seemed to be affected. Trying a couple of times re-uploading and saving the post again seemed to fix it. But not so lucky on the last post it just seems to hang during upload when I try to modify it.

Given that this seems to be happening to the same people repeatedly (I'm looking at you Mnem) and not to just everybody at random, can I suggest that the people who've experienced this post what combination of browser/version/platform that they are using? It has the flavour of being something like a change in platform javascript behaviour, perhaps tied to a particular recent version/update. If my hypothesis is right we should see some commonality between the setups of people that it's happening to, if it's wrong then we won't.

Given that this seems to be happening to the same people repeatedly.

Yes it only effects some of us and some images, but it's not at our end. https://www.eevblog.com/forum/chat/website-error-reports/msg3104478/#msg3104478

I've added a spare rigoltime.png attachment to see if that one changes, I'd already removed and replaced the first one but it changed again. :)

Trying to workaround the bug I only posted one pic/post on my last two posts - but both got affected anyway - post #1 I noticed immediately - had correct thumbnail but opened up the pic from post#2 - I re-uploaded pic to #1 and that fixed it. Both posts were correct 12h ago but now post#2 opens the pic from #1.

Are we being cyber attacked?!

Not that I'm aware of.

Gnif knows about it and is trying to find the time to track this down.  (Remember, he puts in is own time for free to look after this place.)

Given that this seems to be happening to the same people repeatedly (I'm looking at you Mnem) and not to just everybody at random, can I suggest that the people who've experienced this post what combination of browser/version/platform that they are using? It has the flavour of being something like a change in platform javascript behaviour, perhaps tied to a particular recent version/update. If my hypothesis is right we should see some commonality between the setups of people that it's happening to, if it's wrong then we won't.

Nahhhh... it's happening to lots of people. You just notice it more with me because I'm a heavy abuser of visual aids; goes with the territory being the class clown. ;)

I've been trying to find a process which ameliorates the issue; right now I'm doing this:

I make sure I finish the longish process of editing the text of a pic-laden post and click "Review" just before adding pics to eliminate the possibility of a "There are new posts" red flag ducking up my file uploads; this has been going on since long before this latest SMF indignity.  |O  BTW, I have confirmed that it isn't just image files which get borked; I had a .pdf wind up in limbo the same way not too long ago.

Also, I make sure to:

Resize my pics to ~300k or less

Upload 3 or less at a time, and

Wait 10 seconds after the last pic is "uploaded" before I click "POST" or "SAVE" so the process completes as quickly as possible.

This ties in (I think) with the notion gnif proffered a while back that the issue is related to lag in propagation between servers; at first I thought it might have been because I sortof straddle 2 transatlantic trunks here in Toronto, but extensive trial & error found no correlation with whether I was using my VPN (server in New Jersey) or not. :-//

When I DO get a borked pic, I try to fix it by just adding that pic again and linking to the new pic rather than deleting the faulty pic and replacing it. This seems to lessen the likelihood that fixing a post will then bork another older post in the thread. It SEEMS to; that may just be confirmation bias. :-//

Good hunting, gnif!

Some more info:

From the PC I made the #1 and #2 mentioned posts - both pictures are still correct - I can open the page in a new window or restart Firefox or reload the page over and over - and they are still correct.

But if I open the page in a new private window in Firefox - clicking the thumbnail in post #2 shows the pic from post #1. And this is also the case if I open the page from any other PC.

EDIT:

Also just tested - if I log out from eevblog the behavior is the same as I described.

Perhaps the behavior has something to do with the cookies stored on the PC I posted from - I don't know.

I just experienced this image bug with two posts here:
https://www.eevblog.com/forum/repair/old-cnc-machine-memory-board/

The image URLs are:
https://www.eevblog.com/forum/repair/old-cnc-machine-memory-board/?action=dlattach;attach=1021664;image

https://www.eevblog.com/forum/repair/old-cnc-machine-memory-board/?action=dlattach;attach=1021660;image

Note that they are different, but the contents are exactly the same.

HTTP headers of the two for comparison:

Thread-Problems with uploaded attachements!


As mentioned by TV84, this might be a big problem:
https://www.eevblog.com/forum/testgear/new-rigol-16-bit-function-generators-dg800900-series/msg3122658/#msg3122658

As long as only pictrures are concerned, it is simply annoying, compared to the effort you had with making, downsizing (to meet the max. 5MB limit) and last but not least uploading the images to your post.

The problem:
The Thumbnail-Picture is still fine, but the link to it is wrong and leads to a completely false picture. It is somehow messed up with any (!!!) further reply you make in the forum, I guess?!

Here is an example:
https://www.eevblog.com/forum/testgear/uni-t-ut181a-triplett-9065-trend-viewer-question/msg3132148/#msg3132148

The thumbnail of the first pic is correct, but it leads to the picture from my next reply, therefore it was somehow replaced by it, which leads to a mess, as described pictures are gone and the message gets useless...

Probably, it is better to use external image/file hoster, till the problem is solved to avoid a total mess?!


Cheers!
Due to the massive "EEVblog forum attachement bug", I am now using an external picture hoster, till it is solved...

I wonder why some people get less problems...

One thing that might vary from user to user, is how the files are named.   Do you always give the image a unique name in every post (including, being unique across all posts)?

When I post multiple pics they are usually from the same folder and therefor also has a unique name.

I wonder if the problem is more related to the amount of server traffic when you post the pictures/attachments.

This is the 'element code' of my two mentioned posts/pics from a PC that opens same image from both - or shows the error.

When I get access to the PC I made those post from I do the same thing to see if any difference appear.

Code: [Select]
<a href="https://www.eevblog.com/forum/projects/show-us-your-mains-waveform!/?action=dlattach;attach=1021018;image" id="link_1021018-0" onclick="return ILAexpandThumb(1021018-0);"><img src="https://www.eevblog.com/forum/index.php?action=dlattach;topic=240210.0;attach=1021020;image" alt="1021018-0" title="Show us your mains waveform!" id="thumb_1021018-0" style="width:100px;border:0;" data-pagespeed-url-hash="2538578502" onload="pagespeed.CriticalImages.checkImageForCriticality(this);"></a>

EDIT: well the code is exactly the same from the PC that can open correct image - no big surprise there but I'm still puzzled how it manage to fetch the correct image it does not seem to get it from Firefox cache.

EDIT2: so what I am essentially observing is this link:

https://www.eevblog.com/forum/projects/show-us-your-mains-waveform!/?action=dlattach;attach=1021014;image

will open correct image from the PC I posted/uploaded it from and show a sine wave in blue. But if I open it from any other PC it opens the image from my previous post and show a sine wave in red.

All thumbnails are shown correctly from all PC I've tested.

From that link I am seeing a red sine wave.

Note: you should be able to do ctrl+F5 to force a reload from network and not cache, in most browsers. You can also directly access the network, with guarantee of no caching, by using utility like wget or curl.

Yeah I finally manage to clear the Firefox cache - though I had to clear it restart FF and then clear it again. Now the posting PC also fetches the wrong image which is the red sine wave. I didn't clear any cookies so these probably had no effect on this problem.

Also, can we have some way to disable Imgur embeds?

Say I post a link, a raw URL, not an img embed, and that's literally all I want.

There exists no combination of Imgur URL (gallery or direct link) that won't auto embed.  It's way too greedy.

Often I want to refer to links inline with text and this BIG MOTHERFUCKING EMBED interrupts my text, it's ridiculous.

YouTube embeds do the same thing, but there at least you can use a shortened link to evade it (IIRC?).

Image files and attached files corruptions going MAD.....

Example, 3 corrupt images on this thread page:
https://www.eevblog.com/forum/fpga/fpga-vga-controller-for-8-bit-computer/msg3135492/#msg3135492
Scroll down, the errors are over a few posts...

Try expanding the timing diagram in this post:
https://www.eevblog.com/forum/fpga/fpga-vga-controller-for-8-bit-computer/msg3121924/#msg3121924

try expanding the second image in this post:
https://www.eevblog.com/forum/fpga/fpga-vga-controller-for-8-bit-computer/msg3111866/#msg3111866

Or this one:
https://www.eevblog.com/forum/fpga/fpga-vga-controller-for-8-bit-computer/msg3111884/#msg3111884

This one has the wrong image:
https://www.eevblog.com/forum/fpga/fpga-vga-controller-for-8-bit-computer/1075/

This one is also corrupt:
https://www.eevblog.com/forum/fpga/fpga-vga-controller-for-8-bit-computer/msg3107130/#msg3107130

The top example now has 4 corrupt images.  Yes, 1 new one in the time I've been writing this message if you go to the first link and scroll up instead of down.  Those images were there fine yesterday.

Here is another one:
https://www.eevblog.com/forum/fpga/home-made-systemverilog-3-word-zero-latency-fifo-documented-for-beginners/msg3123336/#msg3123336

In fact, over the last week, I've editing my posts, deleting & re-uploading images again & again.
Does anyone know what's been going on?

People! It’s a known issue, and it’s got nothing to do with your browser cache or anything, as it’s purely a server database problem. It seems to be triggered by interrupted posting.

Yes.

A fellow eevBlog member has suggested a possible workaround:

I think there's a problem only with the first attachment slot. If you skip the first one and use the other one it appear to be working fine.


I'm going to try this for a few days and see if it makes any difference.

Obviously the photo links continues to not work.   I tried to delete a picture that was inserted in one post but was being referenced in another.  This had no effect.  So I blew away the entire post which also had no effect.

I'm not sure if they keep metrics on who posts the most pictures but I suspect I abuse it far more than most.   I wonder if I were to start deleting my old posts/images would it help ease the problem?   If so, just let me know and I will start cleaning up my mess.

I was thinking that it's overall just too much data for the software to handle.    Looking at my attachments, there's 121 pages of 25 images/page or over 3000 images spanning 5 years.   That's a lot of images.

This is the latest I know of from gnif when he was available to work on the problem:

...I usually use Firefox on my PCs; I brought up the thread on my iPad/Firefox and still FUBAR the same way, so not a local cache issue. Same behavior in Edge.
 
This may be related to another bug that has been happening for months; when posting multiple images, IF the posting process is interrupted for a new post warning, the damned thing just forgets the first pic. It attaches the rest of the pics normally, but that first one you ALWAYS have to go back and attach again...  [edited for brevity]

Déjà vu: Best enjoyed as a garnish with wine, cheese and baguettes.
SMF doesn't care about the filename, it stores all attachments as a hash of the file contents and references them via a table. There are two possible reasons why this happened:

1) The bug you mentioned
2) The maintenance last night was intended to correct some sync issues between the web servers as the database cluster had lost sync. Normally this would be fine, but there were other factors at play at the same time that prevented them from determining who was the "latest" and both were accepting update/insert queries at the same time (split-brain).

I should have been clearer I am sorry, if this is seen on new posts as of today, please let me know. Feel free to fix any that are messed up from prior.

Since then it has been off & on, though server loading does affect it. It def happens a lot more often on weekends.

I think there's a problem only with the first attachment slot. If you skip the first one and use the other one it appear to be working fine.
