Yes Timo, found "Warning: Killed with signal 15" in the log. What can be "something" that killed dovecot?

Well. There are two problems: First is that it's crashing, which is
clearly a bug. It just shouldn't happen. If you upgraded to v1.1.13
you would probably get a core dump, and that might be useful in
figuring out the crash (http://dovecot.org/bugreport.html), but the
real problem appears to be in the Disconnected reason. "Shutting down"
means that the whole Dovecot is being shut down. Which most likely
means that something killed dovecot master process. Do you see such a
line in logs? Probably "Warning: killed with signal <something>".On Mar 29, 2009, at 11:41 PM, Long Le Dinh wrote:
