    Request going to single server and getting kicked off

      We have a cluster of six servers.But we are observing that all the request is going to one server and due to High CPU Usage member is getting kicked off from the cluster.

      We have Thick Swing clients calling the SSB in the server.
      We are using Comma separated list of servers from client to look up and in EJB we use default clustering algorithm.

      We don't have any error in server log.So i guess some how all calls are going to one server and it gets over loaded and getting kicked off.

      Can you guys give me some poniter on why such a behavior can happen?For me it seems to be some config issues.

      I have gone through wiki/forum but does seem to help

            COPY from the guide for JBoss 4.0.3. It might be help. Not sure.
            "In JBoss 3.0.x, each client-side stub has its own list of available target nodes. Consequently, some side-effects can
            occur. For example, if you cache your home stub and re-create a remote stub for a stateless session bean (with the
            Round-Robin policy) each time you need to make an invocation, a new remote stub, containing the list of available
            targets, will be downloaded for each invocation. Consequently, as the first target node is always the first in the list,
            calls will not seemed to be load-balanced because there is no usage-history between different stubs. In JBoss 3.2+,
            the proxy families (i.e., the "First AvailableIdenticalAllProxies" load balancing policy, see Section 16.1.3.2) remove
            this side effect as the home and remote stubs of a given EJB are in two different families."
