(I'm not sure why but this shows up as a blank message from my

Can you try getting core dumps from apache in those situations?  I had
a similar situation on solaris at one point and had a real time
messing with CoreDumpDirectory (apache) and system core settings to
try and keep all the child dumps around.

I expect that you have some module doing something nasty and it should
show up in the core.
