Hi Timo With the current hg (ed5fa76f0dc7), I get a crash as soon as I append a single message to a dsync replicated mailbox.
Setup is the same as in the thread "dsync replication errors" ( http://www.dovecot.org/list/dovecot/2013-January/070574.html ) Feb 11 15:01:19 doco1 dovecot: imap-login: Login: user=<user1>, method=PLAIN, rip=192.168.23.130, lip=192.168.23.61, mpid=1709, session=<roTpV3PV1wDAqBeC> Feb 11 15:01:32 doco1 dovecot: doveadm: Fatal: master: service(doveadm): child 1713 killed with signal 11 (core dumped) Feb 11 15:01:56 doco1 dovecot: doveadm: Fatal: master: service(doveadm): child 1715 killed with signal 11 (core dumped) bt full is attached.
