sites inaccessible

Just a heads up. Since yesterday I’ve been experiencing a number of 504 errors on the .com txp domains. I also confirmed these with downforeveryoneorjustme.com.

You are not alone! Today while posting in another thread I had 3 or so occurrences.

Re: sites inaccessible

Aye, me too. Gateway timeouts. Usually that’s indicative of a third party / dependent site not responding in time.

Re: sites inaccessible

I contacted Pete earlier and he has now upped memory limits on the server which may have been causing this issue. Please let us know if the problem persists. Ta!

Re: sites inaccessible

Right now, the forum was terribly slow to access (at first). But then accessing the login page, etc and reaching here went quite fast.

Re: sites inaccessible

Some technicals (I’ll write more later): I’ve upped the time out window for PHP on Nginx, and also bumped the memory_limit on PHP.

I’ve also juggled the file format for the hourly forum database backup (which runs ~400MB), so that should improve responsiveness.

Apologies for the turbulence.

Re: sites inaccessible

Post mortem.

Cause of sporadic outage: PHP 7.3 memory_limit was too low. A combination of PHP-FPM (i.e. the glue that makes PHP work with Nginx, in this case) and PHPBU using the same version of PHP, along with a typo in the config file (i.e. memory_limit = 128M should have been memory_limit = 512M) meant there wasn’t enough system RAM allotted to all the stuff that was happening. And there was a lot of stuff happening.

Solution: PHP 7.3 memory_limit has been increased.
