Ok. So, I think there should be some error/warning log(s) in case of network problems at least? How can I switch the logging level of JBM and jboss-remoting and the other related modules ? I can also reproduce the problem and debug it myself. I just need some directions. I have already tried to debug the client side (the consumer), but there are only two threads blocked on a socket.read(). I haven't yet tried to debug the Jboss side of the JBM/remoting.
