Re: beta testing version

I don't have the same luck, sorry to say!

I am running Mandrake linux with OpenWall patched 2.2.17 kernel, dual p3
550Mhz, 1gb memory.
It's a really busy webserver that constantly is running with 10 in load.
Sometime it spikes to ~40-50 in load (the most we had was 114(!)).
I am running postgresql 7.0.2 (from the Mandrake rpm's).

One problem i have is that in one database we rapidly insert/delete in some
tables, and to maintain a good performance on that db, i have to run a
vacuum every hour(!).
I think that db has excessive indexes all over the place (if that could have
anything to do with it?).

Another other problem that is more severe is that the database "crashes"
(read: stops working), if i run psql and do a select it says
"001129.07:04:15.688 [25474] FATAL 1: Memory exhausted in AllocSetAlloc()"
and fails.
I have a cron script that watches postgres, and restarts it if it cant get a
select right.
It fails this way maybe once a day or two days.
I've searched the mailinglist archives for this problem, but it allways
seems that my problem doesn't fit the descriptions of the other ppl's
problem generating this error message.

I have not found the right time to upgrade to 7.0.3 yet, and i don't know if
that would solve anything.

Another problem i have is that i get "001128.12:58:01.248 [23444] FATAL 1:
Socket command type unknown" in my logs. I don't know if i get that from
the unix odbc driver, the remote windows odbc driver, or in unix standard db
connections.

I get "pq_recvbuf: unexpected EOF on client connection" alot too, but that i
think only indicates that the socket was closed in a not-so-nice way, and
that it is no "real" error.
It seems that the psql windows odbc driver is generating this.

The postmaster is running with these parameters: "-N 512 -B 1024 -i -o -S
4096"

But as a happy note i can tell you that we have a Linux box here (pentium
100, kernel 2.0.3x) that has near 1000 days uptime, and runs postgres 6.5.x.
It has never failed, not even a single time :)
