Replication: Can't unsubscribe from shared mailbox

[Karsten Heiken]

Hi,

I am running two dovecot servers active/active.
Everything runs pretty great, except for the replication of subscriptions in a shared namespace.

When I unsubscribe from a folder the subscription instantly re-appears. The timestamp on the subscriptions file is updated, but the entry is still in there.
If the other node is shut down, everything works as expected, which leads me to believe that the subscription is re-applied upon a replicator-run.

I attached a tcpdump of a dsync run.
The only action that was executed was to unsubscribe from the folder shared/weinrot at luis.uni-hannover.de/INBOX.

Is there any other way I might help debugging this?


Thanks,
Karsten
