WORKAROUND

To work around this problem, add indexes or hints to the query to prevent a HASH JOIN operation or a Sort operation in the execution plan. Alternatively, use a MAXDOP 1 hint to cause the query to run serially.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
