I'm running dovecot 20051026 version on Redhat4. I tried to do a stress test. However dovecot dies after I login a few hundred users. I have some error messages in my mail log and am not sure if they are related to the problem.
[root@lms2 imap1505]# service dovecot status dovecot dead but subsys locked
