    High CPU usage Jboss 7.1.1-Final

    Manish Devraj Newbie

      I have deployed application on Jboss 7.1.1-Final and since couple days I am experiencing heavy CPU load upto 180%. This usage is higher both when idle and when application is running and getting accessed. The load on system is not higher.

       

      Application is deployed in standalone non-cluster mode. It is running behind Apache mod_jk cluster (SSL). Highlights of functionality are -

       

      1. Hbase connection

      2. Infinispan cache

      3. HornetQ

      4. Kafka Producer and Consumer

      5. OSGI bundles

      6. Spring modules

      7. RPC calls

       

       

      Attached is thread dump to look at
