    Unable to obtain HTTP Session Replication

    Pradeep Mishra Newbie

      Hi,
      I have set up a 2 node JBoss-4.0.0 cluster.
      I enabled the HTTP session replication by changing the Snapshotmode to instant in jboss-service.xml .
      Also, I made the application distributable.
      The startup showed no error.
      When I brought down on instance that was serving the request, the request got forwarded to the next instance, but the session objects were not replicated/ Lost. I didn't get any error messages,though.
      However, when I stopped the network for that system, I got following errors--
