Gateway Timeout

[silenceheaven]

Every hour the entire board goes out with this error message and only this:

upstream sent unexpected FastCGI record: 3 while reading response header from upstream, client: xxxxx

[info] 274#274: *326933 client 212.228.25.73 closed keepalive connection

 

And I'm not sure exactly why this is happening, or if anyone has run into this issue before. I've disabled any custom extensions but I am unable to resolve this issue.

I can provide configs and whatnot, but I can't find any info about this error.

All other PHP-FPM pools are fine, it's just the ipboard one and only started occuring with 4.3

There are some pitfalls  you should be aware of when using this function.

The script will still occupy a FPM process after fastcgi_finish_request(). So using it excessively for long running tasks may occupy all your FPM threads up to pm.max_children. This will lead to gateway errors on the webserver.

Another important thing is session handling. Sessions are locked as long as they're active (see the documentation for session_write_close()). This means subsequent requests will block until the session is closed.

You should therefore call session_write_close() as soon as possible (even before fastcgi_finish_request()) to allow subsequent requests and a good user experience.

This also applies for all other locking techniques as flock or database locks for example. As long as a lock is active subsequent requests might bock.

I'm gonna comment it out in \IPS\Output and see if that resolves the issue.

I am also using sockets instead of TCP listeners so I don't have the FastCGI keep_conn enabled at all, so the bug that I'm seeing was apparently a big ago shouldn't apply. It's also on PHP 7.2 with Nginx 1.14.0

Nope did not work. Also I have this error in php-fpm.log
