High CPU Usage - WIndows 2008 R2 Server

HI All,

We have a windows 2008 R2 server, the CPU spikes all of a sudden. I think it's the system process that causes it to spike.

There are 8 CPU's on the server and CPU 1 always seems to be 100%, how do i find out whats causing this?

Thank you in advance,

If it is always the first CPU that is spiking then it is a single thread that might be causing the issue.  I don't know of a way to identify which process is using which CPU but next time it happens, check to see if the CPU utilization has spiked on CPU0 (CPUs are counted from 0, you have 0 to 7).

CPU 1 is 100% all the time

In Task Manager, go to the Processes tab, check the "Show Processes from All Users" checkbox, and then sort by either the CPU or the CPU Time columns.  See what bubbles up to the top.  If needed, add a bunch more columns (View/Select Columns) to get other details, such as the command line.

Or, better yet, download Process Explorer from www.SysInternals.com (now part of Microsoft), sort the processes by CPU, and start drilling down to see what it is doing.
