Error warning php-fpm executing too slowly

ℹ️ Support

I encountered some errors related to the php-fpm service causing server overload
At the time of testing, I noticed that php-fpm was processing a certain process that took up a very high amount of CPU.
I check the log and the results appear as below

Services on the server Rocky Linux 9

  • Nextcoud 28.0.2

It would be great to have some more information about the resources of your server and not as a screenshot please but as text in a fenced codeblock.

Then you should try to optimize your www.conf file, as [pool www] is the active pool your nginx is proxied to. I am not a CentOS/Rocky specialist but under Debian that file is located in

/etc/php/${php_version}/fpm/pool.d/www.conf

You can find that file with this command.

sudo find /etc -name "www.conf"

There is a lot of explanation inside of that file that will guide you to optimize it to your needs.

I hope this may help you to solve your problem and to remove bottlenecks.

Much and good luck,

Any errors or warning in the logfiles? Perhaps there is already a reason why it takes so long. Do you see other processes heavily used (e.g. the database)?

Do you have high i/o waits from the database?

For the number or parallel connections/number of users, your RAM usage is really moderate.
