Hello everyone,
We have SQL Server 2008 R2 SP1 and we are running issue with one of the application. When we look at the SQL Server utilization on the server we are seeing one of the CPU core spike to 100 % for about 1-2 minutes and the application freezes during that time.
This very consistent each time it happens. (see the screen shot below) we are just trying to identify the issue? is there any reason where only one core on the server spike but rest of them are OK? where should we begin to investigate? Thank you.
