We have noticed that when the number of imapd processes reaches
about 120, no further connections are possible. We have already
changed the connection limits in /etc/courier/imapd:
MAXDAEMONS=640
MAXPERIP=500
The server load is very load and there are no disk i/o issue when
this happens.
The problem is that the connections do not seem to exit so
those clients who can not connect will not be able to fetch mails.
We end up periodically killing the imapd daemon to reset the connections.
Perhaps there are other parameters that need to be changed in
the qmailtoaster package that need to be changed as well?
Thanks for any info
Richard
