Thanks a lot for your explanation! However, now I am at the beginning again.
You could try doing some tests to see if you can trigger the problem. Or try to reduce the value from 1000 first to 100 and then maybe drop until people start complaning about and raise it a bit higher :)
BTW. What Dovecot version? If this isn't working as expected, maybe dovecot -n output could show something /usr/local
We do not use the most recent version... but was there a bug with this parameter?
I was thinking if you were maybe using some really old version or maybe if you were using v2.0 and if there maybe had been some new bug.
login_processes_count: 8 login_max_processes_count: 8192
Maybe you should set login_process_per_connection=no. http://wiki.dovecot.org/LoginProcess
