This issue only impacts customers with more than 2GB of memory (available only with the Enterprise, Developer and Evaluation editions) where AWE has been enabled and more than half of the total system memory is being allocated to a single SQL Server instance.
This problem does not affect IA64 platforms.
Customers with this configuration should apply this hotfix after upgrading to SQL Server 2000 Service Pack 4.
