SYMPTOMS
When you cancel a remote query that returns many data rows in Microsoft SQL Server 2000, a memory leak may occur. The size of the memory leak depends on the size and the type of data that is being retrieved from the remote server. You may receive an error message that is similar to one of the following error messages in the SQL Server error log:
SQL Server could not spawn process_loginread thread.
WARNING: Failed to reserve contiguous memory of Size= 65536.

810185 SQL Server 2000 hotfix update for SQL Server 2000 Service Pack 3 and 3a
back to the top
CAUSE
This problem occurs because SQL Server maintains a small number of row buffers made up of data that is being retrieved by using remote queries. Typically, these row buffers are freed when the query has finished running. When you cancel a query that is running on the remote server, the batch ends before the row buffers are freed.

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.
