Hi all,
I recently noticed that I continue to receive "allocation failure"
messages from postmaster in /var/log/messages on the server where the
problem occurred.
Aug 17 23:00:51 tms2 kernel: : postmaster: page allocation failure.

Except these messages everything is just fine. The server is a passive
(very rarely queried) hot standby.
Are there any ideas of why and what could it be?
Thank you.
