    Unable to announce backup, retrying: java.lang.NullPointerException during failback

    Pallavi jain Newbie

      I have configured colocated live-backup hornetq server (hornetq-core-2.2.13) embedded in JBoss 7.1.1 two node cluster. Protocol used for clustering is tcp/TCPPING.


      My scenario is


      1. Jboss as with HQ in colocated live-backup  topology - Jboss01 live/ jboss02 backup & jboss02 live/ jboss01 backup

      2. start jboss 01 & jboss 02 both will announc backup

      3. stop jboss01 then jboss02 will failover and will start the backup server

      4. Start server jboss02 again and wait I get

      WARN  [org.hornetq.core.server.cluster.impl.ClusterConnectionImpl] (Thread-2 (HornetQ-server-HornetQServerImpl::serverUUID=9ec98bdb-7888-11e2-9727-005056bf0066-1759482265)) Unable to announce backup, retrying: java.lang.NullPointerException

      5 shutdown jboss02 again Jboss01 will again failover correctly.

      6 Jboss02 will not failback untill unless journal directoires are cleared and both the servers are restarted sequntially.


      I saw similar jira entry for dedicated topology https://issues.jboss.org/browse/JBPAPP-7606


      Any suggestions
