Problems as this are hard to track down. I'll give you a few thoughts
what you could do next. Maybe it helps, but I can not guarantee it.
 - Play around with MaxRequestsPerChild. A typical value
   outside of 0 is 10000. I guess that's also the default,
   but not in your setup.
 - Did you compile apache yourself? Give it a try.
 - Have you tried to get the lock-up in a lab setup with
   apache bench or some other load generating tool?
   Guess, this would help.
 - You disabled mod_perl2 and mod_php. This sounds as if
   you would not really need them. (Or you sacrificed 
   functionality :)
   Disable all modules which you do not really need. Definitely
   all of them. If you can boil it down to threadsafe modules,
   then you might give it a try with another mpm.

Good luck - and keep us informed on how it goes.
