CPU Time has gone Mad?

[fimchick]

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!

How many CPUs are in the box?

I am betting there are 4.

4 CPUs doing nothing, 1 sec per processor x 4 = 4 seconds.

I have a dual CPU box that counts 2 seconds of idle time for every one second clock time.

Idle cpu time is nothign to worry about Means the CPU isnt doing anything.

If its flaky you may want to investiage and repair your exchange datafiles.
