Timothy Bish commented on AMQCPP-315:
-------------------------------------
Anything is possible, the CMSTemplate code is not as well tested in the Unit
tests as it should be so we could be missing some bugs there. Have you tried
using synchronization around the call to CmsTemplate::receive() so that the
threads are forced to not access that resource at the same time?
> Advisory messages do not work with multiple listeners

> Key: AMQCPP-315
> URL: https://issues.apache.org/activemq/browse/AMQCPP-315
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Affects Versions: 3.2.2
> Environment: Windows, ActiveMQ 5.3.1
> Reporter: Helen Huang
> Assignee: Timothy Bish
> Attachments: activemq.log, AdvisoryMessageListener2.zip,
> vs2005-build.zip

>
> We found that the advisory messages do not work as expected when there are
> multiple consumers listening to the same advisory topics.
> We have three applications, AdvisoryMessageListener, MessageListener, and
> MessageSender.
> AdvisoryMessageListener listens to the following two topics:
> ActiveMQ.Advisory.Consumer.Topic.cpp.itemLookup
> ActiveMQ.Advisory.Producer.Topic.cpp.itemLookup
> MessageListener listens to topic: cpp.itemLookup
> MessageSender sends messages to topic: cpp.itemLookup
> If there is only one instance of AdvisoryMessageListener , then everything
> work fine. We can get the advisory messages when we start/shut down
> MessageListener or MessageSender . However, when we start a second instance
> of AdvisoryMessageListener , it seems to knock out the existing connection of
> the first AdvisoryMessageListener. The first instance can no longer receive
> any advisory messages after that.
> This problem could be related to the problem reported in jira item
> "AMQCPP-314 Starting app with Com using cms destroys connection of other app.
> New problem with recent lib version". However in our problem, we do not have
> any COM layers.
