I have read every other thread about this error with no luck.
I'm running Nginx 1.12.2 with PHP-FPM 5.6 on RHEL 6
I am getting these errors on any/all pages of my site. It is not related to slow requests. I have witnessed it personally and I immediately get a 500 error page without any waiting.
It affects both POST and GET requests.
I am not running any opcode caches (that I am aware of) I checked all config files, phpinfo() as well as php -v and did not see any mention of opcache or opcode.)
I have turned on catch_workers_output in PHP-FPM. I am not receiving any PHP errors
I have plenty of memory available and there are no errors in the system logs about memory, file descriptors or sockets.
Tried pm_max_requests with both high and low numbers
Not running xdebug plugin
Seems to happen at random times, even in the middle of the night when we aren't very busy at all.
I'm desperate for a solution to this issue which has gone on for months now.
Here's some of the information asked for in the comments below:
