I have modified my codes so that all transactions are being started and commited within the UserActivityManager MBean which is using the TreeCacheAop service to cache all user activity. Any EJB methods which access this UserActivityManager are marked with a NotSupported trans-attribute in the ejb-jar.xml in order to get around any potential nested transaction problems. My hope was that this would solve the deadlock problems that I was experiencing, but alas no such luck. I have no problems with the replication, but the deadlocks are still occurring with some frequency. Fortunately my application can handle these without failing, and no data seems to be corrupted in the TreeCacheAop. In other words after the TimeoutException is caught my application just hums right along as if nothing happened. Unfortunately it does cause an error to appear to users, and the user then needs to reinvoke the command which was unsuccessful, and this is something I'd really like to avoid, so I need to minimize or eliminate these deadlocks.
Is there anything in the below stack trace which points to anything out of the ordinary with my configuration which might be causing this to happen ? Below the stack trace I list the jboss-service.xml which is being included in the SAR. Thanks for any insight. --James 12:05:54,012 INFO [STDOUT] org.jboss.cache.lock.TimeoutException: rsp=sender=10.10.10.23:39435, retval=null, received=false, suspected=false | 12:05:54,013 INFO
