---------------------------------------
The example and my code work well, now. Thanks !

> Key: AMQCPP-126
> URL: https://issues.apache.org/activemq/browse/AMQCPP-126
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: CMS Impl
> Affects Versions: 2.0.1
> Environment: tested on Windows 2000
> Reporter: olivier renaud
> Assignee: Timothy Bish
> Fix For: 2.1

> When a network error occurs, I want to clean up all the created objects and
> close the connection and the session.
> So, when I catch an exception (activemq::io::IOException), either created by
> from producer.send, or by an asynchronous notification on the
> ExceptionListener object set for the Connection.
> However, closing ressources (Consumer, Producer, or Session) always crash the
> application. This can be seen with the Example code in ActiveMQCPP sources :
> - run the example program so that it connects to a distant host (not
> localhost)
> - physically unplug the network (or shutdown the network connection), and wait
> The program stops with the following message :
> {quote}
> ...
> Sent message #334 from thread 1216
> Sent message #335 from thread 1216
> Message #335 Received: Hello world! from thread 1216
> JMS Exception occured. Shutting down client.
