Guys,

I have a situation in SQL 2008 (SP2) 64 bit where the CPU remains static at 35-40% consumed by SQL Server exe process, I have tried to check the processes consuming the CPU none of them
come from the queries against the user created databases.

SELECT * FROM sys.SYSPROCESSES
--where spid = 55
ORDER BY cpu DESC

lastwaittype cpu
PREEMPTIVE_XE_CALLBACKEXECUTE 173294828
LAZYWRITER_SLEEP 2568812

Is there anyway to find out what is causing high cpu (there are no sql jobs running during this time), any inputs or suggestions would be helpful.

Thanks

I'm confused. Why do you think 35-40% CPU utilization by SQL Server is high? That sounds about average actually.
