Subject: [GENERAL] fatal error in databaseHowdy:
Running PostgreSQL 7.2.1 on RedHat Linux 7.2.
I'm having a problem trying to identify some of the causes
for the following errors:[snip]
test=> select count (*) from t_testob;
FATAL 2: open of /raid/pgsql/data/pg_clog/0373 failed: No such file or directory
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: NOTICE: Message from PostgreSQL backend:
The Postmaster has informed me that some other backend
died abnormally and possibly corrupted shared memory.
I have rolled back the current transaction and am
going to terminate your database system connection and exit.
Please reconnect to the database system and repeat your query.
Failed.

I have a log file that captures some errors (my debug level is 2)
and it says this:[snip]

When it says, 'corrupt shared memory', I'm *hoping* this has nothing to do
with 'physical memory'.Can someone tell me how I can stress test PostgreSQL so that I
can find out what the error is really referring to?Thanks!
