Thank you Adrian, I didn't find FAQ about this error. I only have visited this url: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossMQIGetJava.net.SocketExcept... But the exception is not the same: 2006-12-12 17:41:21,752 DEBUG [org.jboss.mq.il.uil2.ServerSocketManagerHandler] Exiting on IOE java.net.SocketException: Connection reset instead of (my exception): 2007-07-25 09:47:13,656 DEBUG [org.jboss.mq.il.uil2.ServerSocketManagerHandler] Exiting on IOE java.net.SocketException: Socket closed. And in this FAQ was written: Reason: The JMS client is not closing the connection. The connection is reset by the OS when the VM exits. My JMS client is closing the connection in a finally block. Thanks in advance. Mika View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4067700#...
