# prefork MPM
<IfModule prefork.c>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 30
MaxRequestsPerChild 0
</IfModule>
Mine "/etc/apache2/apache2.conf" (on Lenny) contains this section:
<IfModule mpm_prefork_module
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
so may be you should try adjusting the IfModule argument?
The Apache page [1] also lists "mpm_prefork_module" under "module
identifier".
