I am analyzing memory dumps for high CPU usage but all I see is most of the runaway threads show a constant time of 0 days 0:05:48.921 the second and millisecond change offcourse and mostly all call the Microsoft Practices EnterpriseLibrary ConfigurationChangeWatcher. We are using MS Ent Lib 6 for logging. I do not understand how would that all be related to High CPU usage can anyone help me analyze the dumps and throw some light.

I see this pattern through out the call stack.
