Hi list;
We encountered "java.net.SocketException : Sockect close " when we upgraded jboss from 3.2.3 to 3.2.5 on one of our production server. The application compose of a servlet (recieve request and jms client) and a mdb. Message are send a text message. Although request got process by mdb, yet this exception keep on occuring.Has anyone from the list have any idea why this is happening? Below are the log
