    MDB singleton stops working

    Armin Haaf Newbie

      We have a mdb singleton in out jboss as 5.1 cluster on a clustered queue using the
      @Depends(jboss.ha:service=HASingletonDeployer,type=Barrier") annotation.

      Sometimes we loose this singleton when shutdown/startup a node.

      No more consumer is on this queue.

      It did not get up again without stopping all nodes and start the cluster from scratch

      what can we do to get this singleton mdb up again without restarting the whole cluster or better how can we do to avoid the problem
