SYMPTOMS

When you run several concurrent queries against a Microsoft SQL Server 2005 Analysis Services database, the Analysis Services service may stop unexpectedly.

CAUSE

This problem occurs when the data cache mechanism lets multiple threads access the data cache registry and alter the data cache registry at the same time. When multiple threads access the data cache registry and alter the data cache registry at the same time, memory corruption may occur. When memory corruption occurs, the Analysis Services service may stop unexpectedly.
