I have a few long running processes on apache and when the server gets a bit of a load they all seem to couple into 3-4 processes. I've tried setting the MaxRequestsPerChild to 1 and that works, but spawning new processes all the time is expensive.

Here is my current configuration:

<IfModule prefork.c>
StartServers       25
MinSpareServers    50
MaxSpareServers   50
ServerLimit      512
MaxClients       50
MaxRequestsPerChild  10
</IfModule>
<IfModule worker.c>
StartServers         25
MaxClients        50
MinSpareThreads     50
MaxSpareThreads     125
ThreadsPerChild     50
MaxRequestsPerChild  10
</IfModule>
