Hi,
I am having the same problem as Brian. AOLServer will crash after a few
clicks and the log file registers a ns_realloc error.
I am running AOLServer 3.2+ad12 on HPUX 11 with PostgreSQL 7.0.3 and
pgdriver 1.1 (from openacs.org). I started aolserver under gdb:

And the server crashes. Like Brian, it happens sporadically. Sometimes I
can click away for minutes and sometimes the server will crash after a few
clicks.
I've tried looking at the swapfile size, vmstat, and ulimit. It doesn't
look like I am running out of memory. My data ulimit is at 64Megs.
Do you guys have any ideas on how I can resolve this issue? Thanks.
