How to find out the current setting for FcgidMaxProcesses on Apache?

While asking this question, I feel that it may be dumb - but I have no idea at the moment...

How to find out the current setting for FcgidMaxProcesses on Apache?

Background

I experienced the following error: mod_fcgid: can't apply process slot for ...

My Apache2 allows MaxClients=500 and the default configuration for FcgidMaxProcesses is 1000, according to mod_fcgid docs. Therefore, the MaxProcesses should not be the limiting factor - but before starting to play around with the settings, I would prefer to check the current value. So ... how do I?

Thank you

Settings

# apache2.conf
<IfModule mpm_worker_module>
    StartServers             2
    ServerLimit             32

    This is the purpose of mod_info. On the server-info page, you will see all the possible configuration options and if they are customized. If there is no custom setting, then it is the compile-time default, which does seem to be 1000 as confirmed by the documentation and source code (line 48).

    Note: don't use the Location /server-info or create a link to your mod_info Location or you'll end up in Google like this server: http://dice.csail.mit.edu/server-info#mod_fcgid.c
