The PromiscuousTraffic bug is still listed as open in the Sun database: http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4701650. Since the exact cause of this issue is not clear, for safety reasons we recommend using different ports. If you've tested your environment thoroughly and are convinced it's not an issue and won't become one with different equipment configurations you may adopt, then you might get away with not changing it. But we recommend that you do change it. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020659#...
