In the future, please post the full log message, it will save time. :-) The code logging what you posted is not the web session replication service. It's the jboss:service=DefaultPartition mbean from cluster-service.xml. Please enable DEBUG logging for category org.jboss.ha. You should get more information on what's happening during the delay. The state transfer timeout param controls how long the service will wait for a state tranfer response from the other node. After receiving the response it still needs to integrate the received state. That can take time, although several minutes certainly seems excessive. The debug logging should help show what the problem is.
