Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.


By default, the affinity mask for SQL Server is set to zero, permitting the SQL Server worker threads to use any available processor. When the affinity mask is set, the SQL Server worker thread is affinitized, and the worker thread can only use one specified processor. The addition of the SQL Server startup trace flag –T8002 treats the affinity mask like a process affinity and invokes the SetThreadAffinityMask function. However, the SQL Server thread affinity is set to all bits supplied in the affinity mask when the trace flag is used.

For example, if the affinity mask is set to 0x3 (processor 0 and 1) and the trace flag –T8002 is not used, half of the worker threads are affinitized to processor 0 and the other half are affinitized to processor 1. However, when the trace flag –T8002 is enabled and the affinity mask is set to 0x3, the worker threads are affinitized to both processors. If you set the trace flag and the affinity mask, you can limit the overall processors that SQL Server uses.
