Hi,
I have a dovecot 2.0.7 installed on ubuntu 12.10 and often in dmesg I see "init: dovecot main process (7104) killed by KILL signal", I must restarted dovecot, because I can't access to mailbox.
Server hardware: 2x1TB disks 4GB memory 1xCPU 2,4GHz HARDWARE RAID 1 Mailbox ~ 1k

Any ideas what's wrong, where is the problem?
