Howard Gao commented on JBMESSAGING-1706:
-----------------------------------------

Hi Piyush,

This kind of exceptions are usually caused by the server side clean up of failed connections. For example, the network undergoes some temp failure and cause the remoting layer lease timeout, it then notifies the jbm server of the event and the server cleans the related connections up. But for the moment it is still possible the client haven't got the notification and continue operations with the 'bad' connection.

To verify you have the same case, look up the logs for any information saying the connection failure information.

To reduce the situation, you can adjust your remoting parameters (lease timeout) according to your network condition. For a JMS client if such exceptions occurred and your client need to continue to work, you can close the old connection and create a new one.

> The issue is that JBM intermittently (ie. when processing large amounts of messages, when bringing up/shutting down nodes in a cluster) throws a HeuristicMixedException. Once it does, that node in the cluster 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 am using a workaround by having a separate monitoring program that reboots the node whenever it gets stuck in this HeuristicMixedException state.
> The JBoss ESB team have also had to implement a workaround: https://jira.jboss.org/jira/browse/JBESB-2484
> Others on the forum are seeing this too: http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4241134#4241134
> According to Kevin Conner of the ESB team, Howard worked with them on a workaround: https://jira.jboss.org/jira/browse/JBPAPP-1642, but the issue persists.
