[dovecot] Error: child 12625 (imap) killed with signal 12

Hi!

I have tried to install dovecot as my imap service on my FreeBSD server.
At first all looked fine and worked flawless. But after a while i started
to get errors. The imap process dies with signal 12 when the client tries
to check the contens of the folder.

dovecot: Apr 07 09:55:17 Error: child 12625 (imap) killed with signal 12

Any ideas what may cause this problem?
