Hi guys,
The JBoss Messaging guys suggested I post here (original thread here http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241134#4241134).
I'm having a hard time finding good documentation on javax.transaction.HeuristicMixedException. JBoss Messaging (and the old JBoss MQ) seems to throw this exception intermittently while processing large volumes of messages in a batch (say, 2000 messages over 3 cluster nodes):
javax.transaction.HeuristicMixedException at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commitAndDisassociate (TransactionImple.java:1431) at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction .java:137) at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.commit(BaseTransactionManagerDeleg ate.java:75) at org.jboss.resource.adapter.jms.inflow.JmsServerSession$XATransactionDemarcationStrategy.e nd(JmsServerSession.java:657) at org.jboss.resource.adapter.jms.inflow.JmsServerSession.run(JmsServerSession.java:243) at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:205) at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:260) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619)
