Hi,
I have sql server 2008 R2 SP2 installed ,the memory utilization is normal but sqlserver.exe process is taking 97 % of CPU even when no application is accessing it,no job is running, in fact its new server for testing purpose. After looking into sysprocesses i found out that CPU hoggiing resource was "SOS_SCHEDULER_YIELD ",Is it CPU pressure
my machine has two CPU's both are single core.
