AS and client are running on the same machine. Have you any hints what we should think about it? Thanks,    Kevin -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559683#559683] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
