Solution Verified - Updated -


  • JBoss not able to form UDP cluster when it operated on Openstack (especially when nodes are located in remote VM server)
  • TCP cluster is working fine at the same env.
  • CacheException like 'Initial state transfer timed out for cache ' occurs at JBoss EAP server.log
Caused by: org.infinispan.commons.CacheException: Unable to invoke method public void org.infinispan.statetransfer.StateTransferManagerImpl.waitForInitialStateTransferToComplete() throws java.lang.Exception on object of type StateTransferManagerImpl
Caused by: org.infinispan.commons.CacheException: Initial state transfer timed out for cache default-server on <node_name>
