Hi all,
I have few of these messages in server log:
ERROR: out of memory
DETAIL: Failed on request of size 262143996.
STATEMENT: VACUUM ANALYZE tablename
There are few of them, always the same request size(?) but different two
databases (out of 100+) and few different tables (pg_listener,
pg_statistic and few slony tables). Vacumm analyze is issued by
pg_autovacuum.
We're also seeing strange behavior of listen/notify in possibly
corrupted database: there are notify events being received by listen
process which the process didn't subscribed to. Can this be connected?
I've done little research in mailing list archives and I found possible
cause: table corruption caused by flaky hardware. Does it sound about
right? Are there any other possible causes?
What can be corrupted? How can I check it? How can I correct it? What
are possible consequences of this corruption? How can I investigate it
further?
It's Postgresql 8.0.6 on Linux.
Any help would be greatly appreciated.
Thanks,
Kuba
