SQL CPU usage


I have a SQL server running multiple databases for different applications hosted on different servers and in the last day or so, the CPU consumption is very high on the SQL server, getting even to 100%. I'm trying to figure out which database connection causes this but don't really have a whole lot of experience with SQL. Any SQL gurus that can tell me how to look into the server and find the culprit?

Thank you very much!

Can you execute a "SELECT @@VERSION" and post the results here? It will include the SQL Server version number and build - there are a handful of known/patched issues, and knowing the version number can easily see if you're affected.

Knowing the version will also give the experts a place to start recommending diagnostics. There are a few places to check, but since you're not a SQL Server DBA specifically, I'd want to give pretty specific instructions instead of general "check here and here"-type advice.

How is the memory consumption? Usually when CPU is on 100% is because the memory was fullfilled first.
What is the server configuration? And the memory configuration for the SQL Server?
What else do you have installed in the server?
