Hey Folks!
We had a very disturbing issue on our Production server which killed our business systems for a fixed interval everyday.
Business was unable to compile thier work during this time and every user was complaining.
The Server CPU utilization would spike to 80% and more and remain constant the entire interval of almost an hour.
We investigatied on what was causing all this by using performance monitors and SQL Profilers .
And finally the culprit was a group policy which would clear the cache and browsing history on every users machine exactly at a ascheduled time, which would trigger enourmous number of request on the DB Servers for SharePoint and K2 applications.
This in turn choked the servers CPU utilization.
Thanks
