I ran into this problem with alpha4 on Solaris 9. I doubled the following dovecot settings:
login_max_processes_count = 256 (was 128) login_max_logging_users = 512 (was 256)
and the problem went away. I carried these numbers forward into alpha5, and it has been working fine.

For now, I bumped the 'open files' shell limit in the dovecot start script to 1024 (default was 64 which sounds a bit on the low side).
64 files as default for any process is absolutely weird.

head -1 /var/run/dovecot/master.pid| wc -l 49on any process and think twice about setting the max open files to such a strange value.
What, 1024? The default of 64 which has been quite sufficient for Dovecot 0.99.x until now, and still is for other server processes?
