Hi All,
We are using active MQ in our product and running into an issue.
1. We have a tomcat web server that launches ActiveMQ server(broker)
2. We have an applet that runs on IE which creates an ActiveMQ client
3. This applet posts a heartbeats messages every one minute on a Topic
We are running into an issue if on the same PC a separate applet ( it could
be any applet ) is run on an IE browser while my applet is running.
Now if I close the browser running my applet and relaunch my applet again,
first 3 heartbeats are posted and after that I get the following exception.

Any idea what is going on ?
If I close all my IE instances and restart my applet everything is fine
again.
Any help is appreciated.
Thanks
