For a few minutes before the crashes, the app server gets about 35-45 requests per 
minute.  Other hardware/config info:

        Dual 1.25GHz G4
        1.75 GB memory
        PostgreSQL has it's own drives for data & logs.

        THREADPOOLSIZE=25
        LOGGINGLEVEL=3

        All caches/buffers are quite large and no swapping occurs.


Is THREADPOOLSIZE too low for this traffic?

Also, I have logging turned up to see if a particular piece of code is being executed 
before the crash (or some kind of pattern).  But if the last part of the log is lost 
on a crash, then I won't get that info and could turn logging back down to 1.
