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 the hotfix package is replaced by any other hotfix package
  • Whether you must make any registry changes
  • The files that are contained in the hotfix package

SYMPTOMS

In Microsoft SQL Server 2000 Service Pack 4 (SP4), new diagnostics do not capture the thread stack when the SQL Server User Mode Scheduler (UMS) experiences a nonyielding thread. Additionally, the thread context variable is not populated with the expected thread stack information. When this problem occurs, an error message that is similar to the following is logged in the SQL Server error log:
<Date> <Time> server Error: 17883, Severity: 1, State: 0
<Date> <Time> server Process 0:0 (0) UMS Context 0x002A7058 appears to be non-yielding on Scheduler 1.

CAUSE

This problem occurs because no thread ID is associated with the idle thread that is considered to be the nonyielding thread.

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.
