High CPU usage when system is idle

[Franc v/d Westelaken]

Hi,

when my server is idle (99% cpu time for system idle process), the
server responds stil jerky and the cpu usage in the status bar and on
the performance tab is reported at 20%...

Is there a way to determine which is causing this ? It sure isn't a
process. I've disabled almost all services but that doesn't help.
Could it be a driver that is causing the high cpu usage, if so how can
I determine which one....

Franc.

For detailed information on CPU usage you can run Performance Monitor
- The Processor object counters will show you detailed information about
the CPU
- The Process object will show you detailed information about each process
running on the machine (including their CPU usage)

Are you running Outlook Express at all?

Hi,

using the performance monitor I was unable to determine the process.
However, using the process explorer from sysinternals, it appears that
the Hardware Interrupts Process is taking 15 to 20% of cpu time.

???? I don't get it what you mean ?

You can choose to answer the question or not it is up to you. Outlook Express comes with Windows.

You must be kidding right, I know what outlook express is, but what
does it have to do with this topic ?

 

[Franc v/d Westelaken]

And no, I'm not using it ...

OK. Outlook Express msimn.exe to be exact can cause this issue. Plyers Plyers Plyers.

Ok, thanks for the follow up. I did some testing today. It appearred
that one of the network cards of the Proliant DL360 was faulty, as
soon as I disbaled the card, processor usage went down to 0-1%,
swapping cables didn't matter. Finally I pulled out the disks and
placed them in another DL360 and in that one the problem doesn't occur
with the network card enabled, so it must be a hardware problem. I'm
calling HP tomorrow...

Well I was close? LOL. Sorry I am glad you got it figured out Outlook Express or no Outlook Express.
