Hmm. Maybe it's opening a new auth connection for each user? I'll check it out later.

This should be solved somehow. I guess Dovecot doesn't warn that your file limit is lower than the client_count (default=4096). Run ulimit -n 8192 or something before starting Dovecot. I'll add a check for that.

This can be expected.

Half a minute later. I guess the process was idle-killing itself.

I guess this has to do with the crash and restart of auth process. I'll see if I can reproduce and maybe avoid these somehow.
