I got a crash on a production server this morning following during
very heavy load. This is postgres 9.1.3 on Linux (going to 9.1.4
asap). I didn't catch a core dump it doesn't look like one would help
anyways. Server is virtualized quad on vmware. Here is the log I
have:

connection because of crash of another server process
2012-06-25 09:08:24 CDT [postgres@postgres]: DETAIL: The postmaster
has commanded this server process to roll back the current transaction
and exit, because another server process exited abnormally and
possibly corrupted shared memory.
The plpgsql errors are expected. The background here is I have four
threads constantly loading small databases in bash and there was one
long running ETL process in the background as well.
