[jboss-user] [JBoss Messaging] - HeuristicMixedException: cause and remedy?

[kennardconsulting]

Hi guys,

I'm having a hard time finding good documentation on javax.transaction.HeuristicMixedException as it relates to JBoss Messaging. JBoss Messaging 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(BaseTransactionManagerDelegate.java:75)
  |         at org.jboss.resource.adapter.jms.inflow.JmsServerSession$XATransactionDemarcationStrategy.end(JmsServerSession.java:657)
  |         at org.jboss.resource.adapter.jms.inflow.JmsServerSession.run(JmsServerSession.java:243)
  |         at org.jboss.resource.work.WorkWrapper.execute(WorkWrapper.java:205)
  |         at org.jboss.util.threadpool.BasicTaskWrapper.run(BasicTaskWrapper.java:260)
  |         at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)
  |         at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
  |         at java.lang.Thread.run(Thread.java:619)
  | 

The worst thing is, once the exception is thrown, that node is effectively dead. No more messages get processed. My app has multiple queues, but once one queue on the node fails (say, the e-mail queue) then all queues stop working (say, the reports queues): they all report HeuristicMixedException whenever a messages is sent to them.

I had this same error with JBoss MQ, and upgraded to JBoss Messaging in hopes it would be fixed. But no luck! Can anybody suggest why this error happens, and whether there is some setting to automatically recover from it? If I manually restart the node it works fine.

Regards,

Richard
