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.
