STATUS
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.
MORE INFORMATION
AWE memory permits applications to use more memory than is available through standard addressing by dynamically mapping the views of the non-paged memory to the standard address space. SQL Server was unmapping hot pages, causing page contention on "hot" pages that are unmapped. SQL Server was also pushing higher mapping activities than expected. You can use the AWE counters to monitor Microsoft Windows 2000 AWE activity in SQL Server.
REFERENCES
For more information about AWE, see the "Using AWE Memory on Windows 2000" and "awe enabled Option" topics in the SQL Server 2000 Books Online.
