Are you sure that logging is not turned off? If it is, then once the bootstrap completes, you get no more console log messages.
The other possibility is that you have some network issues. The best way to track that down is to do a Java thread dump and see what the thread(s) are waiting for. This might require that you dig through the JBoss AS source code to find out what it is doing, but the stack traces in the thread dump will help you with that.
