[jboss-user] [Clustering/JBoss] - Buddy Replication Issues

[@jb0ss]

Hi Friends,
I am using jboss 4.0.5GA
I have the following properties se for my node to enable buddy replication.

<attribute name="BuddyReplicationConfig"> 
  |  <config> 
  |                 <buddyReplicationEnabled>true</buddyReplicationEnabled>
  |                 <buddyLocatorClass>org.jboss.cache.buddyreplication.NextMemberBuddyLocator</buddyLocatorClass>
  |                 <buddyLocatorProperties>
  |                     numBuddies = 1
  |                     ignoreColocatedBuddies = true
  |                 </buddyLocatorProperties>
  | 
  |                 <buddyPoolName>default</buddyPoolName>
  |                 <buddyCommunicationTimeout>2000</buddyCommunicationTimeout>
  | 
  |                 <autoDataGravitation>false</autoDataGravitation>
  |                 <dataGravitationRemoveOnFind>true</dataGravitationRemoveOnFind>
  |                 <dataGravitationSearchBackupTrees>true</dataGravitationSearchBackupTrees>
  |   </config>
  | </attribute>

But when I start two nodes and shutdown one node, the application crashes. Failover does not work.I am not able to understand why.

If I disable buddyclustering and let the session replicate across all nodes
then application clustering works fine for failover.

This is my jboss console log:-
