Hi everyone,

Well, here's an update. VERY preliminary tests show that the PostgreSQL
message in question is not caused by the child exiting. I have a 1
MacClients prefork Apache with MaxRequestsPerChild of 5 and I have a
'warn' statement on the PerlChildExitHandler to alert me when the child
exits. The message doesn't appear when the child exits (unless there's
some buffering going in the PostgreSQL logs, which is likely.)

However, the message does appear when I stop Apache. Hmm, very
interesting. (It may be worth noting that I'm running on OS X, I still
need to test on Linux.)=20

I will revisit this sometime in January. We have year-end things to do
here at work and it's absorbing all my time. Bleah. I'd rather play with
Apache. :)

Thanks,
--Joel
