Hi I have seen this type of error on the forums but none seems to help. We have a Jboss-4.2.2.GA running Jboss-messaging-1.3.0.GA the system is RedHat EL4.5 . the error i get is : ERROR [ServerThread] Worker thread initialization failure java.io.EOFException | at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:526) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:369) | at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:165) I've used Jboss-4.2.1.GA and did an upgrade but this did not solve this crushes i even try to switch the jboss-remoting.jar with the 4.0.5.GA witch saw on this thread here http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4063410#... and here http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091683#... but with no luck . any help would be good .
