Symptoms: The Call Services global error log starts to grow rapidly, and server performance is significantly hindered. This is triggered by an error that occurs while when an attempt is made to log an error. Inspection of the error log reveals a pattern of exceptions similar to these:
01/08/2007 08:10:59, SERVER ERROR: An error occurred while trying to log a different error encountered while attempting to log an event. A listing of the original error follows this one in the error log. The error was: java.lang.IllegalStateException: getAttribute: Session already invalidated ... 01/08/2007 08:10:59, SERVER ERROR: An error was encountered while attempting to log an event with the ID "javaApiError". The error was: java.lang.IllegalStateException: getAttribute: Session already invalidated
Note: The text after The error was: in these examples can be different in your environment and circumstances. The key phrase to look for is this: An error occurred while trying to log a different error encountered while attempting to log an event.
Resolution: This issue has been resolved internally, and will be included in the next post-3.6.4 maintenance release of Cisco Unified Call Services. In the interim, apply this workaround to each deployed voice application:
Edit the file data/application/ActivityLogConfig.xml and remove (or comment out) these lines:
<event id="systemError"/> <event id="javaApiError"/>
Tests indicate that these two events have the potential to trigger this scenario. If you do not allow the ActivityLogger to listen to them, the situation can be avoided.
