Increasing max connections - Mailing list pgsql-novice

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?
