    strange cluster problem:broadcasting the same node id

    leo cheng Newbie

      I have two nodes to form a cluster under fedora linux 12. If I close then start the first node three times, the second node will complain same broadcasting node id received.

       

      The first node command line and log:

      Did I mis-configure my nodes? I need HornetQ to reform current message system, so it is very important to me. Can anyone help me?

       

      Thanks.

          I patched one file, now it stops complaining after repeating 2 times. But the following WARN message still exists, does it really make significant?
