Hello!
I am having a little problem with Jboss MQ. Everything seems to be ok, but some times I get this error. it seems like the client is not able to stop JMS connection, and that leads to this error.
Both Client and Server are behind the firewall. I opened every port needed on the server side and am wondering if I need to open any port on the client side? Did anybody have such a problem?

I think I could reproduce the error again. I do not know if it a bug, but when the client misses net connection then at the server side I get "Connection reset" but this does not remove the client from the list of loggedInClientIDs.
This could be an explanation. Any tips?
