Joshua -

I understand what the settings mean.  My reasoning behind these settings 
is that Apache would be able to quicker respond to a request if it 
already had a child waiting for the connection.  If for some reason this 
site got an additional 40 hits in one instant, Apache would deal with 
those by sending them to children, and then when that is established, it 
would create more children in anticipation for new connections.

Regardless, where might I be able to find more information about this 
error?  I'm very curious now.
