I noticed that my server this morning was not responding. received nginx error page after waiting some time for the page to load. I decided to restart php-fpm because I figured there was an issue serving the php pages. After doing this the website worked per usual.
I'm wondering what could cause this type of behavior?
I checked the error logs for PHP-FPM and there was nothing aside from this.
NOTICE: [pool www] child 25155 exited with code 0 after 1028.418645 seconds from start
And my PHP-FPM config settings look like
pm = dynamic pm.max_children = 200 pm.start_servers = 16 pm.min_spare_servers = 16 pm.max_spare_servers = 32 pm.max_requests = 500
My server is a X3440 with 16GB of ram running Centos 6. Any input would be greatly appreciated.
