We are having the same problem in a production system running on JBoss 4.0.4 on Windows 2003 server. Our Message driven bean stops receiving messages, althought the message queue has many messages to deliver. Up until now the only workaround we found is to restart the application server. Any ideas on what is causing this problem? Is there any other workaround? Thanks in advance View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4155623#...
