Postgres 8.1.2 crashed now how to figure out why?

Hi, I have a production PostgreSQL database used by a 24/7 application.  I have it running on RHEL 4.2 server running PostgreSQL 8.1.2 on SUN v20Z servers & thankfully running RH Cluster server (helpped me out today :)  This morning it decided to crash but was brought back online by the cluster software within a matter of seconds. The thing is I am left with the situation of trying to work out why it happend. It appeared to run out of memory (Out of Memory: Killed process 22431 (postmaster).
) so could be a Postgres bug. Does any one have idea's of where to start?  Below is the output during the incident logged in the /var/log/messages file

Thanks,
Sel

I would not point fingers at Postgres right away - nautilus and gnome-terminal were killed as well for the same reasons. I would start with profiling overall memory usage and looking at what application actually ate up all your memory - it could be that it wasn't Postgres.

There is also a possibility that you are running too many child processes with Postgres and they run out of memory.

When out of memory your system kills processes. This is normal.
After postmaster dies use your creativity with "ipcs -a" and "ipcrm -m" to clean up
Post output of "free" and "hdparm /dev/hda" and top lines of "dmesg | less" down to memory sizes.
