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.
