Yeah, that reasoning looks correct upon review of my httpd.conf.
StartServers is set to 3, MaxSpareThreads is set to 10 and
ThreadsPerChild is 25.  Therefore, it'll start three processes and
then immediately kill two of them off.

So, can we make the default httpd.conf a little more sane?

Either do:

StartServers = 1

or

MaxSpareThreads = StartServers * ThreadsPerChild

I'd probably prefer to see StartServers = 1.  Patch inline.  -- justin
