I have a server which should be idle and I get messages telling me that the CPU is over 90% for over 15 minutes. Specifically SQL Server is at 99% I looked in the SQL Server log and saw these messages: Lots of them every 5 to 15 minutes
DBCC TRACEON 208, server process ID (SPID) 54.
Does anyone know what this message means? I have looked in books online and they don't list the 208 flag. IF I do a DBCC TRACESTATUS I get nothing.
Any help would be appreciated. Thanks in advance,
Brian

Thanks, Ok I think I figured out what is happening.
I have recently installed Quest's LiteSpeed and it probably sets that on for updating the statistics in its central repository. Makes sense now.
The CPU spike was caused by a new process I put in to purge backup/restore history and it was run for the first time last night and took 15 minutes. Now it takes 16 seconds. Much better.
Thanks again
