what causes a /usr/bin/php-cgi process to start?

hello - what is causing one single /usr/bin/php-cgi to start up?

my problem seems to be excessive php-cgi processes in memory occasionally.

Howdy,

A php-cgi process is what happens when a user browses to your website.

If your system is getting overloaded, it may mean your site is receiving more traffic than your server can handle. You may want to lower the MaxClients option in Apache in order to restrict how many users can browse your site at once.

Also, if you have any PHP modules enabled that you don’t need, disabling those would reduce how much memory each of those PHP processes uses.
