Any possibility there is a call failure when you invoke on one of the servers, such that the client proxy is failing over to the other server? You could then see a pattern where the client sees there are 2 servers, contacts one, the call fails so the client removes the server from the target list, contacts the other server, call succeeds but server sees the client target list is out of sync with the server, so it reestablishes the 2 targets, etc. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3999595#...
