correctly).Oncethe application starts to open connections it looks that the each postmaster associated with the
connectionis not exiting as fast as was before. I can follow up with a ps -aux capture if you think that's helpful.
Tillyesterday all was working smoothly for about 2 years. It looks like the postmasters are not finishing of if they do
takesa good while to finish. Also I've seen that the swap increases. I never use to have swap used. I don't have space
problemsnot errors in the syslog.Am I running out of memory and all gets delayed by the swap handling ? I have the
feelingthat I spin around my tail. So these processes are taking all the CPU and memory and they hold for too long just
doinga select. The traffic didn't increase by any me
ans so one can say that causes the problem - at one point it sustained 4 times more traffic without problems.Hope this

Could you please send your messages as plain text? Your mail client is
doing something foul to the plain text alternative incorporated in the
multi-part message. It's almost unreadable this way.
