SQL Server Forum / DB Engine / SQL Server / July 2008strange problem: cpu 100% on sql server with no activity
Hi All I met really strange problem. On 1 host we have 3 instances running in VM machine. Yes, it was not configured properly, but... default instance would shout 100% cpu right after startup. I checked all event log records, errorlogs, dump logs - all look inocent. No option changes, nothing. Other 2 instances are just fine. Any clue? Can you look at sys.dm_exec_requests or master..sysprocesses while the CPU is pegged like this? How about running a lightweight trace on startup? Not everything that consumes CPU will necessarily have anything at all to do with error logs...

I think it was just unproportional load on the instance, no technical problem. > Hi All > I met really strange problem.
