java.exe utilize 99% of CPU cycles on Cognos Server during normal interaction with Cognos Portal

Troubleshooting

Problem

Cognos portal appears to hang if the user performs any simple action

Symptom

Any navigation action is taking a very long time for the user. Users have to wait till any invoked actions are completed during which time the Cognos portal becomes unusable and users are not able to perform any other actions.

CPU utilisation also hits 99% for the java process invoked by the BiBusTKServerMain process

(BiBusTKServerMain process is involved with running the report.

While running the report new objects keep consuming Java heap memory which in turn spikes the memory utilisation. These new objects include report objects such as Lists, and or Crosstabs etc. for which memory is allocated within the Java heap.

Saving report outputs involve Authentication and Content Manager (CM) services are Java based processes and consume JVM memory.)
