Alright, I just noticed this on our Exchange box that is running on Server 2003. The CPU Idle Process Time is incrementing by 4 seconds. So instead of going from 1 minute 5 seconds to 1 minute 6 seconds, it jumps to 1 minute 9 seconds, then 13 seconds, then 17 (there is no delay between the time count, so it's not sitting there for 4 seconds and then updating, it's incrementing 4 seconds of time per each second in real-time)...Has anyone seen/heard about this? The 3 PDC's are fluctuating between 1 second and 2 second increments, but this one is jumping by 4! Can't seem to find documentation on this anywhere. It's got me a bit worried as the server has been acting a bit flaky lately... Thanks!
