Are there any network firewalls between the hosts?
You maybe experiencing a firewall connection timeout.
You might also try the property
this might prevent a firewall to drop the connection.
No, there is no firewall.....
I tried this too..... i faced this issue in Jboss 7.1.2.
Now i switched to Jboss 6.1 EAP, there i am not facing any issue.
