replication: sync_client on master stops after restarting the replica

[Marcus Schopen]

Hi,

always when I have to reboot the replica or its cyrus the
synchronization on master side stops, /var/lib/cyrus/sync/log fills up
and I don't see a "/usr/lib/cyrus/bin/sync_client -r" process anymore.

/var/log/mail.err on master when restarting replica:

Sep 27 10:06:28 master cyrus/sync_client[1023]: Error in do_sync():
bailing out! Bad protocol
Sep 27 10:06:28 master cyrus/sync_client[1023]: Processing sync log
file /var/lib/cyrus/sync/log-1023 failed: Bad protocol

When I restart cyrus on master side, synchronization starts again.

Is there another way to get synchronization working again?

Ciao
Marcus
