    Jboss hangs at Core system initialized

    Asif Iqbal Newbie

      I cannot start jboss. I downloaded the jboss-4.2.1.GA.zip on my Sun Fire X4100, 8G ram and 2 2.4Ghz Dual Core AMD Opteron.

      I am running sol 10 x86 release 6/06. Java 1.5.

      Here is where it get stuck

      Any way to start in DEBUG mode to see why/where it gets stuck?

      I am running the exact same code on another sol 10 x86 6/06 on Ultra 20 and it starts just fine

          Take a thread dump to see where it is hanging. My guess is that it is waiting for some network response. Debug messages show up in the server/default/log directory.

            How do I do a thread dump?

            Here are the last few lines of the boot.log

                  It does not respond to QUIT signal. Actually the only signal it responds to is KILL signal. It ignores all other signals aparently.

                    Try using an 1.5 JDK instead.

                      Sorry, just now saw that you used a 1.5 JDK earlier and then switched to 1.6.

                          Because both the OS and the JVM come from Sun, and because the JVM is hung to the point where you cannot send it a QUIT signal so that you can get a JVM stack dump, I recommend that you contact Sun to find out what you can do to diagnose this problem.
