Hi, my syncserver suddenly refused connection from its master this evening. The master/slave setup is running without any problems for half a year now. On slave/replica side I found in /var/log/mail.err Sep 11 23:51:19 replica cyrus/syncserver[27328]: refused connection from xxx.xxx.xxx.xxx On master side /var/log/mail.err: Sep 11 23:43:33 master cyrus/sync_client[31324]: couldn't authenticate to backend server: no mechanism available I restarted cyrus on slave side and replication started to work again. I couldn't find anything weird in the logfiles on slave or master side, so anything to be worried about? I'm running cyrus 2.4.12 on Ubuntu 12.04 LTS on both sides.
