Re: Autovacuum running out of memory

[Jason Lustig <lustig@xxxxxxxxxxxx>]

There isn't any more error message than this... it simply repeats every minute or so, which is really quite strange. And the user & db is really blank in the log, I didn't trim it (if I did I would have replaced it with dummy values).

I'm using pg 8.2.4 on Linux 2.6.15.

Whenever I turn on Autovacuum on my database, I get a ton of error messages like this in my Postgres log:

Oct 16 06:43:47 [2897]: [1-1]  user=,db= ERROR:  out of memory

Oct 16 06:43:47 [2897]: [1-2]  user=,db= DETAIL:  Failed on request of size 524287998.

It always fails on the same request. When I turn off autovacuum, they go away. However, when I run VACUUM FULL manually, I don't get this error.

Is there nothing before this giving the error message some context?

Is the user and database really blank, or have you just trimmed those?

What version of PG is this, and running on what O.S.?
