Apache + mod_fcgid does not spawn/persist processes

Question

I have apache 2.2 running with mod_fcgid installed, but each request seems to spawn a new process instead of having a pool of workers. Phpinfo confirms fastcgi is working:

But no worker processes, a new process is spawned per request:

The built in server-status handler confirms "Total FastCGI processes: 0".

Am I wrong in understanding what mod_fcgid should provide? I figured just installing the module is enough to have the worker processes spawned automatically.

Answer 1

For reference, the issue was the MPM being used, it looks like prefork isn't compatible. Switching to worker fixed it.
