Subject [jira] Commented: (AMQNET-194) Async error occurred: javax.jms.JMSException: Unmatched acknowledege when Acknowledgemode of Transactional used
Date Fri, 16 Oct 2009 18:09:52 GMT

    [ https://issues.apache.org/activemq/browse/AMQNET-194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=54796#action_54796
] 

Timothy Bish commented on AMQNET-194:
-------------------------------------

Well it would be pretty easy to take the fix for this one issue from trunk and backport it
so you could go that route.  There have been some pretty significant fixes go into trunk though
since the 1.1 release so it could end up being more stable but as its still a moving target
you'd probably want to find a snapshot of trunk that works and just stick with it until the
official 1.2 release.  

Its my hope to get 1.2 released sooner rather than later but I want to try and clear up as
many of the outstanding issues as I can first.

The more people that jump in and test out trunk the better it will be when we do finally get
it released so I encourage you to try it out and see what kind of results you get.

> See http://www.nabble.com/Async-error-occurred--%3E-ActiveMQ-5.2-and-NMS-td25474605.html
for a primer to this issue.
> After troubleshooting this,  it appears that if a producer sends 65535+ messages to the
broker that the consumer gets into an infinite loop after consuming 65535 messages.  
> I will be attaching a test case for this.  Run a producer and a consumer, send 100,000
messages and the test case fails at 65535 messages consumed exactly.
> What appears to be happening is that the NMS provider (or ActiveMQ 5.2) is hitting the
upper bound of a ushort and then starting all back over again sending message acknowledgements
from message #1.  This message was already dispatched though and the broker lot shows an error
that the message is not in the dispatched-list .
> The consumer shows a message acknowledgement going out.
> These errors repeat infinitely it seems.  Once the 65535th message errors out then it
starts all over again at the 1st message.
> Notice the ProducerSequenceId growing beyond 65535.  I can't seem to avoid this error,
even if I reinstantiate the producer sporadically.
> At the beginning of the source code I have included a loop which shows the behavior of
incrementing a ushort beyond 65535.  The variable resets to the lower bound as expected.
