[Dovecot] Command died with signal 11: "/usr/libexec/dovecot/dovecot-lda"

[spamvoll at googlemail.com]

im not sure if i enabled core dumps

im using Centos 5.5
i echoed "'DAEMON_COREFILE_LIMIT="unlimited"' >> /etc/sysconfig/dovecot"
and restarted dovecot
no core files

but i dont have any killed messages in my logs anyway
like: dovecot: Apr 23 11:16:05 Error: child 86116 (imap) killed with signal 11
only " (Command died with signal 11: "/usr/libexec/dovecot/dovecot-lda")"
