I am experiencing database server crashes quite frequently (sometimes,
*daily*), and I am having hard time identifying what could possibly be
causing them :-(
They seem to be happenning kinda randomly, I was unable to attribute
them to any specific database activity going on at the time...
The postgres log looks like:

2003-06-10 13:53:33 [1609] NOTICE: Message from PostgreSQL backend:
The Postmaster has informed me that some other backend
died abnormally and possibly corrupted shared memory.
.....
It does not even produce a core file after this - just silently exists,
and restarts itself.
Could somebody please point me to any clue what could possibly be wrong
with it?
This is 7.2.1 - I know, I need to upgrade.
Working on it, but it is going to take a while, and at the time being I
would greatly appreciate any ideas on what I can do about this thing.
Thanks a lot!
