Dear list, I am having an issue like this http://www.dovecot.org/list/dovecot-cvs/2014-September/024898.html with my current dovecot 2.2.18 Concret: doveadm -Dv replicator replicate -p high -f info throws an I/O Timeout error and the only thing I can see are some lock issues: Error: Couldn't lock /var/vmail/info/.dovecot-sync.lock: Timed out after 30 seconds Can I debug the communication one level deeper? I replicate over a somewhat slow DSL connection. I had the some problem with dovecot 2.2.9 and after upgrading to 2.2.15 everything went smoothly, just a wild guess, maybe the timeout_reset was removed again? Well, doesn't look like it: https://github.com/dovecot/core/blob/master/src/doveadm/dsync/dsync-ibc-stream.c or https://github.com/dovecot/core/blame/master/src/doveadm/dsync/dsync-ibc-stream.c Some debug hints would be nice.
