Have you checked the logs (are you logging for POP3) to see what they might
show? Sounds like someone is connecting, but not terminating the connection
properly, leaving IMail with a bunch of open POP3 connections. That you have
to restart multiple times is kind of strange, too, almost as if the source
of the connections is still doing whatever it does. You might be able to
verify this by attempting a connection and looking at the last number, as
you showed us earlier. If the current number of connections is high (don't
know how many users you have, but I would think anything above 20 is at
least starting to get too high).
I have seen something similar, but with SMTP service and that was caused by
the user having 'Audit' enabled which ultimately caused a big log file, that
slowed down IMail response. That was found using PerfMon and looking for a
larger than normal 'Processor Queue' (should be below 2 and would average
5-8, when this was happening!). Once the Audit log was cleared, the problem
would go away. Log would 'fill up' in about a day or so, so it did have the
long periodicity like yours.
So if we apply similar methods, something is causing the POP3 service to
'collect' open connections, or something is slowing down POP3 servicing the
connections, so they do not close in a timely manner. Not sure where one
might look, but attached is a PerfMon setting that you can try to observe
'Processor Queue'. If the graph stays between 0 and 20, then not the
problem. If it occasionally goes above 20, OK, too. Sustained time above 20
indicates CPU has a long queue, which implies that it is not finishing tasks
in timely manner. Contact MS to learn more about meaning and solutions.
HTH!
