Re: PostgreSQL crashes - Mailing list pgsql-admin

Hi,

It just happened again, now with 8.4, so it seems like the fix mentioned
below didn't really help.

Does anyone have an idea what could cause it?

As a reminder, the log is below.

Thanks,
Moshe.

The second problem is most likely going to be resolved by this recent
fix:
http://archives.postgresql.org/pgsql-committers/2009-05/msg00085.php

I have no idea what is provoking an exit(128) though.
