Title: Server Error Reports
Post by: gnif 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.
If none of the above hold true, please post a detailed error report, the more information the better. Things that help are:

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.
Title: Current Server Status
Post by: gnif 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/ (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 (http://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.
Title: Re: Server Error Reports
Post by: gnif on August 04, 2017, 05:21:38 am
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.  :-//

So false alarm but it did give me a sick feeling.

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:
Title: Re: Server Error Reports
Post by: Ian.M on August 30, 2017, 08:48:38 am
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.

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.

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".

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.

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.

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).

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

Still occasionally running into the (I think) backup problem, but it's early today. Happened about 4 minutes ago (21:45 UTC), normally it happens around 10 minutes from now (22:00 UTC).

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!

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/ (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.

Post by: gnif on March 19, 2018, 02:46:23 am
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.

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.

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.

Hit Next or P2 and the page defaults to a Revise Search page, not the next page as one expects.

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.

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"?

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.

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 (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.

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 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

    onclick https://www.eevblog.com/forum/chat/website-error-reports/new/?topicseen#new:1 (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.
