Scott,
Thanks for your reply. I have found the problem and it appears to be with our firewall
situation. Well I found that connections initiated from server were being denied since
our clients are behind firewall themselves. Opening up a client box did resolve this
issue.
But this is not an option for us unless we know which ports on the client the server
is going to connect to. Can you suggest how to achieve notifications from server in a
situation where client is behind a firewall.
I am posting the thread dumps from the run that hangs.
I hope you can throw some light on how to resolve this issue or some workaround.
Thread dump follow:
