Dovecot sync issues

I have numerous email domains with email accounts reporting the following error.
dovecot: dsync-local([email protected]): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync

doveadm replicator status '*' produces no fails on slave on either server.

I have Ispconfig 3.1.11 with Debian 8.9, With database replication, unison, and dovecot to sync emails this is a recent issue on a machine that has been in service for a long time.

Any suggestions would be greatly appreciated, and as always thank you for your great work.

 

this might be a bug in jessies dovecot package, try jessie-backports to upgrade to a newer version of dovecot ( according to mailinglist:https://www.dovecot.org/list/dovecot/2014-November/098894.html )

and is https://wiki2.dovecot.org/Replication an option maybe? Rumors say it's faster than unison.

edit: ah yeah, don't know why I always ignore these warning signs trying to sell it doesn't work

 

Thank's Till

 

Hi ztk.me,
Many thanks I am running 2.2.13 so I will consider the backports, however I'm also having a read on the replication.
Cheers

 

we have no problems with dovecot on jessie or stretch. check the status on both servers - are you really running one server as a slave or is this a "master-master" for dovecot?

 

Hi Florian, thank you for your response.
I believe it may be "master-master"

 

I think, you can ignore the warnings. I see this from time to time for a mailbox in the logs, too. I would say, as long as the replication state is ok (all mailboxes are in sync), don't think about it.

 

Thank you Florian.
