Then I commented the listen line, and things got better, but not good enough yet. Strange, uh?
I never tried that.
Just for the record: My mail server is running super fast! The problem happens only at specific moments, twice a day, only.
specific moments? Which and what are the spesifics?
If I remember correctly, I made logs of the number of file descriptors of the "dovecot" process; each time the number _almost_ reached the max (say one or two are not allocated yet), I saw the stalls _and_ when I manually logged off users (kill -15 imap-process) the number did not decreased. Well, not much anyway. Sort of, it looked like a fd leak.
Since I have ulimit -n in my init.d, no such problem came up again. The previous ulimit was lower than the max Dovecot could handle.
