Question

Why was the cpanel_php_fpm service automatically restarted on my server?

Answer

It is important to specify that the cpanel_php_fpm service is the internal service used by cPanel itself for tools and addons installed to cPanel. The cpanel_php_fpm environment is not used to serve any pages from user websites, it is used for things like WP Toolkit and Roundcube.

The cpanel_php_fpm service is restarted often to help administer updates to the tools that run within it. For example, when WP Toolkit has a software update, it will need to restart the service in order to apply the changes.

You can find the restart requests logged in cPanel's logs by searching for the relevant terms as shown here:

grep -Eir ".*start.*cpanel_php_fpm.*install-rpm.sh" /usr/local/cpanel/logs/*
