Hi Brian, Thanks for your response. We tried increasing the SyncReplTimeout to a value greater than LockAcquisitionTimeout as follows: <attribute name="SyncReplTimeout">30000</attribute> | <attribute name="LockAcquisitionTimeout">20000</attribute> But still we are getting the same error. Not sure what is going on. Any idea what could be wrong? Thanks Raghu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037532#...
