Thread: Increasing max connections

I'm running 7.0.2 on HPUX 10.20.  I'd like to use persistent connections from
my web server, but find myself with too many backends as a result.

I tried using the -N 96 -B 192 options for postmaster, but the backends seem
to die mysteriously if I have any more than 32 max backends.  I'm suspecting
I need to change some limit or kernel parameter.  What is most likely the
culprit?

Hm.  I've run many more than that on HPUX 10.20 ... possibly you are
running out of swap space or kernel file table slots?  Or just plain old
MAXUPRC (processes per user) limit?

The failures might be less mysterious if you look in the postmaster's
logfile (you are not starting it with -S, I hope, else you won't get
any log output).
