SUMMARY

This article describes the following about this hotfix release:
  • The issues that are fixed by the hotfix package
  • The prerequisites for installing the hotfix package
  • Whether you must restart the computer after you install the hotfix package
  • Whether you must make any registry changes
  • The files that are contained in the hotfix package

SYMPTOMS

Consider the following scenario:
  • In Microsoft SQL Server 2000, you execute a single query, or you execute multiple concurrent queries.
  • Each query returns several levels of nested derived tables.
  • Each derived table contains aggregations.
In this scenario, you may experience the following symptoms:
  • Each query takes a long time to compile.
  • The SQL Server scheduler stops responding (hangs).
  • The computer that is running SQL Server consistently has high CPU utilization.
  • Several error messages are logged in the SQL Server error log. These error messages have error code 17883.

    Note The system server process ID (SPID) for these error messages corresponds to the SPID of the single query or to the SPIDs of the multiple concurrent queries.

RESOLUTION

The installer does not install this hotfix correctly on x64-based systems. This installation issue occurs when the following conditions are true:
  • The system uses the Advanced Micro Devices (AMD) AMD64 processor architecture or the Intel Extended Memory 64 Technology (EM64T) processor architecture.

    Note This issue does not occur on systems that use the Intel Itanium processor architecture.
  • The system is running a 64-bit version of the Microsoft Windows Server operating system.
  • The system is running a 32-bit version of SQL Server 2000.
We have corrected this installation issue in later builds of SQL Server 2000, starting with version 8.00.2244. When a customer who is running SQL Server 2000 on an x64-based system requests this hotfix, we will provide a build that includes this hotfix and that can be installed correctly on an x64-based system. The build that we provide will be version 8.00.2244 or a later version.
