I need some help interpreting the following error.

00:22:47 WARN [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=mnfriasql10/380240, BranchQual=, localId=380240] timed out. status=STATUS_ACTIVE
00:22:47 ERROR [BeanLock] Thread[RMI TCP Connection(46065)-10.150.145.36,5,RMI Runtime]Saw rolled back tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=mnfriasql10/380240, BranchQual=, localId=380240] waiting for txLock

1) Could this be the result of a database deadlock or is this a lock that is internal to jboss itself?
2) Is there any way to trace what is locking? I am using sql server.

Any help is appreciated. Thanks in advance
