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):

The worst thing is, once the exception is thrown, that node is effectively
dead. No more JMS 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 message is sent to them.
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
