    Concurrent TimeoutException when running multi clustered server

    Haytham Salhi Newbie

      Hi,

       

      I am performing an experiment with the following details:

       

      1- I run 4 nodes as follows:

      ./standalone.sh -c clustered.xml -Djboss.node.name=nodeA -Djboss.socket.binding.port-offset=100

      ./standalone.sh -c clustered.xml -Djboss.node.name=nodeB -Djboss.socket.binding.port-offset=200

      ./standalone.sh -c clustered.xml -Djboss.node.name=nodeC -Djboss.socket.binding.port-offset=300

      ./standalone.sh -c clustered.xml -Djboss.node.name=nodeD -Djboss.socket.binding.port-offset=400

       

      And the cluster is setup without any issues.

       

      2- I initialize the default distributed cache with my own data (each entry represents an employee associated with organization) and everything works fine.

       

      3- In the client side, I run a somewhat large number of clients (about 64 clients). Each client open its own connection with the cluster. Then each client starts reading from that cache concurrently. At the beginning of the run, everything seems to work fine but after about (5-10) secs, the cluster above raises that something went wrong. For example, one node logs the exception below several times although I tried to increase the max-threads attribute as well as the replcation-timeout (don't know if they are related though) in /standalone/configuration/clustered.xml but it did not work. I attached the clustered.xml as well as the logs for all four nodes.

       

      Can anyone advise please? Why does the cluster crash when the number of clients is somewhat large? Is there a problem here or there?
