    JBoss(Cluster) shutdown on HPUX

    ws tuzi Newbie

      Jboss 3.23, HPUX 11, JRE 1.41-06
      I am using the shutdown -S command or Ctrl+C to shutdown the jboss ("all")in HP Unix.
      But the jboss is not stopping properly after sometime in shutdown process,it hangs . and when i list the processes using ps comman i can still see the jboss process running.

      I found that occured at the time of"2005-03-14 16:43:54,164 DEBUG [com.cvicse.inforweb.ha.jndi.HANamingService] Stopping AutomaticDiscovery".
      I shut down JBoss properly after commenting HAJNDI service from cluster-service.xml.But I must use HAJNDI for EJB cluster.

      I looked up the code of the org.jboss.ha.jndi.HANamingService.stopService().It calls stop() function of HANamingService$AutomaticDiscovery.Then it calls java.net.DatagramSocket.close() function,here the server hangs up.

      Folowing code is DatagramSocket.close() :
      public void close() {
      synchronized(closeLock) {
      if (isClosed())
      return;
      impl.close();
      closed = true;
      }
      }
      public boolean isClosed() {
      synchronized(closeLock) {
      return closed;
      }
      }

      I suspect that perhaps synchronized of closeLock result in this case.but I don't know how to investigate that at this point.
      Perhaps the HPUX mechanism of UDP Socket is differ form other OS?
      What I can do to ensure shutdown JBoss(cluster) on HPUX correctly?

      Any info or sugesstion will be helpful.

      Thanking in advance.
