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.


Kindly take a look over this directory in first act for find out more logs :


Try with restart in gracefully way (WebServer), try with stop and start back-end server engines, check the disk space then check ram and cpu usage .

Usefull commands :

free -m
df -h

either if still problem exists inform me here will help you out with future suggestions as well .

PS: You can share logs here , i'll take a look over them ...

Have Great Day Future Friend ;-)

  • Thank you very much for the feedback. I have set-up server monitoring so next time this happens I can send you more details. The there's a few TB's of free disk space so this wasn't the cause. I"ll update you here if it happens again. – Elise Crane May 8 '18 at 19:04
