Dsync issues since 2.3.11.3.
Hello!
I've started seeing intermittent dsync failures since upgrading Dovecot to 2.3.11.3-3 (CentOS 8 using the official Dovecot repo).
Sep 27 17:49:04 host dovecot[130]: dsync-local(user@host)<5GWFD2CmcF+TJwAAsNnMGQ>: Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 66543 no longer in transaction log (highest=66547, last_common_uid=46346, nextuid=46347)) Sep 27 17:49:04 host dovecot[130]: dsync-local(user@host)<5GWFD2CmcF+TJwAAsNnMGQ>: Error: Remote command returned error 75: ssh <options> doveadm dsync-server -u user@host
It seems to happen at random times to random users.
My setup has 2 servers - users are connecting to the main server and the secondary server is just for backup - noone is actually connecting to it.
Any suggestions?
Thanks! Reio

Today I encountered a new error amidst the previous ones:
dsync-local(user@host)

For the last few days the problem has been fixated on a specific mailbox.
There are no errors at all in the logs of the secondary server nor any further errors on the primary.
Would it be a good idea to run doveadm force-resync on the primary server (or both?) for that mailbox?
Thanks, Reio
