Thanks for your answer. Okay, I understand. So this is not an unusual
behavior of my setup. When I check processes now I see a
"/usr/lib/cyrus/bin/sync_client -r" process running as user cyrus. So a
simple

  su - cyrus -c "/usr/lib/cyrus/bin/sync_client -r"

should start the sync again. Right?

May be monit could help. Otherwise the replica needs shell access via
ssh ... hmmm.

Ciao!
