Guest Heinrich Moser Posted March 6, 2008 Posted March 6, 2008 Hi! Our Windows Server 2003 is quite slow recently and shows an unusual lot of kernel CPU activity in Task Manager (the red line in the CPU utilization graph). The server has more than enough RAM. Is there some way to find out which (driver?) is causing this? Thanks, Heinzi

You will be able to see what is taking the time.

Well, it's not the "one process gone wild" type of problem. The CPU is acutally mostly idle, but still the machine is extremely slow. I thought that the fact that, *when* something is done, much time is spent in kernel mode, could be an indication to the real problem (probably a hardware problem, which is why I was curious about which part of the kernel is involved in this). Greetings, Heinzi

Anything in the event logs? Any high network traffic? Any application hogging lots of memory (or handles)? -- Brian Cryer http://www.cryer.co.uk/brian
Guest fregan Posted April 30, 2008 Posted April 30, 2008 Re: High kernel CPU usage i noticed the same thing on one of our servers this morning. the task manager only shows user mode processes, not what is using up kernel mode processes. still searching for answers on this one... -- fregan ------------------------------------------------------------------------ fregan's Profile: http://forums.techarena.in/member.php?userid=47822 View this thread: http://forums.techarena.in/showthread.php?t=927082 http://forums.techarena.in
