[Dovecot] 487 imap-login processes - is this ok
Hi,
recently I checked our mailserver for some more tuning and optimizing and noticed, that currently I do have 487 imap-login processes and I'm asking myself if that's o.k.
We do have about 1.000 user in total and not everybody is currently logged in.
May be this is o.k. but if not, what might I check?
We run the dovecot package provided by redhat EL 5.8 dovecot-1.0.7-7.el5_7.1
Thanks for any comment or suggestion.

Older versions of dovecot (all of v1) can under some circumstances screwup and leave hung login processes, this more often than not occurs if you have network issues, requiring a restart of dovecot to clear them. Timo has apparently, IIRC, worked around this for v2.x and it should not happen.

Normal in "high-security mode": http://wiki.dovecot.org/LoginProcess
Most of those 487 processes are probably handling SSL traffic.
