I have run into the same error I think. jboss-4.0.3SP1 [TransactionImpl] Transaction TransactionImpl:XidImpl[FormatId=257, GlobalId=cestestap/1732, BranchQual=, localId=1732] timed out. status=STATUS_ACTIVE [AbstractInstanceCache] Unable to passivate due to ctx lock, id=2007960 Did you ever resolve this problem? Is it just a JBoss configuration problem or did you have to make changes to the application running on JBoss?
