Re: Performance issues on Windows Server 2008 R2 and Windows XP clients

We are having performance issues on one of our SharePoint 2010 server .This is a Windows Server 2008 R2.

Application keeps running smooth even with top user hits and search crawls. 

But some times even with less than 40 % loads , we get around 100 % cpu usage.

Assuming this is not something custom code , but environmental / configuration issue , I have jotted down few of the top most errors .

Please help me point out the top most culprit of these :
