Did you get a look at the process table before you took the machine
down?  Theorically, if some of the Apache processes hit a common
deadlock, it would keep spawning new servers which would hit the same
deadlock and the load would skyrocket like you describe.  

I don't remember if kdb is in PR3, but if you could get a back trace of
the deadlocked processes, that might be helpful.
