Обсуждение: statistics buffer is full on heavily loaded 8.1.4 db.

We have a 4x 2.4ghz Opteron box w/ 8 gigs of ram running a very busy pg
8.1.4 server.  Upon startup we see around 15-20 "statistics buffer is
full" messages and they repeat at random times throughout the day.
During peak times the box sometimes seems to grind to a halt.  Any thoughts?

Do you have

stats_command_string=on

in postgresql.conf as that might cause this error.

If it is truned on please turn it off and then try starting your server.

Thanks,
