CPU utilization is 100%

  • Hi All,

    I have a problem with SQL SERVER, i am using SQL SERVER 2008 & WIN SERVER 2008. Always i am getting 100% utilization alerts.

    When i check task manager it showing 85% SQL SERVER is using than i check 'SP_WHO2' than some users are in SLEEPING status & there CPU utilization is 10%, when i killed that particular SPID then my server is coming normal mode.

    Tel me know what is the exact issue & how do i fix it?

    Thanks in Advance....

  • I would recommend reading chapter 3 of the Accidental DBA Guide (link in my signature below).

  • Have you checked the excution plan for that particular SPID you just killed? I have the same problem before and it caused by index missing. After i add the index back, the sql server became normal. So you may could check yours.

  • Hi,

    I checked it is development server, i can't use profiler while they using server. If i use on same time Server will hang.

  • You dont need profiler to find the execution plan.

    You just need to use 2 DMV's to find the plan from the system tables or 3 if you want the SQL Query as well

    select query_plan, * from sys.dm_exec_requests

    cross apply sys.dm_exec_query_plan (plan_handle)

    cross apply sys.dm_exec_sql_text (sql_handle)
