Can you try mapping the machines IP to the hostname in the etc/hosts file. For example, if the IP is 10.107.70.70 add this following line to the file (or whatever is the hostname): 10.107.70.70 fedora.sbe-online.com By the way, this looks something to do with the Remoting module of JBoss. The suggestion of adding this entry to your hosts file is based on some of the forum posts that i saw over there when i googled. One of them is this: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4098486#... View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4146164#...
