ERROR;[ACTIVE] ExecuteThread: '35' for queue: 'weblogic.kernel.Default (self-tuning)';putString
 org.jboss.cache.lock.TimeoutException: Replication timeout for  X , Y , Z

I am  using JBOSS cache in JBoss Common Classes 2.2.14.GA deployed on Oracle Service Bus which is in a 2 X 4 clustered environment
JBOSS cache config file is given below. Pl suggest appropriate changes.to config file
