      We upgraded one Confluence yesterday from 2.6 to 3.0.1. After upgrade the Confluence started showing following error,

      Database is being updated by an instance which is not part of the current cluster. You should check network connections between cluster nodes, especially multicast traffic.

      Environment in which Confluence was installed is not clustered. This was fixed be restarting Confluence. This error appeared this morning again and here is what logs show,

      2009-10-01 14:19:00,216 FATAL [DefaultQuartzScheduler_Worker-0] [confluence.cluster.safety.ClusterPanicListener] handleEvent Fatal error in Confluence cluster: Database is being updated by an instance which is not part of the current cluster. You should check network connections between cluster nodes, especially multicast traffic.

      This Confluence uses MySQL DB. Is there some fix for this problem?

      Best Regards,
