High CPU usage Jboss 7.1.1-Final
manishdevraj Jan 31, 2013 12:54 PMI 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
