Unfortunately this still doesn't show what is happening.
04:16:47,426 DEBUG [org.teiid.TXN_LOG] (Worker2_QueryProcessorQueue116) before resume:org.teiid.dqp.internal.process.TransactionServerImpl@f6169a8(Xe0IqM/m7WFe LOCAL ID:TransactionImple < ac, BasicAction: 0:ffff2238cb8c:-15cd65da:56fce01a:3f status: ActionStatus.ABORT_ONLY >)
Indicates that the transaction has been aborted - but there doesn't appear to be an explicit action by Teiid, such as a call to cancelTransactions or rollback that would cause this. If there are no other Teiid related errors/warnings in the logs, then you'll need to double check with JBoss transactions logging to see if there is a timeout or other issue that is aborting the transaction.
