This is happening once a rather large batch process commits ie a PLPGSQL
function from within cron.

I have had a good look through groups and most of the time it seems to be
related to a vacuum.

In this circumstance it is causing a peer process job that useses
persistant connections to receive a SIGPIPE signal.

Can some one please advise us can we stop the table filling? Or can we stop
the SIGPIPE?

Thanks
