FIX: Memory mapping leaks when a 32-bit process runs on a Windows Server 2003 Service Pack 1 (SP1)-based computer (917587)


The information in this article applies to:

  • Microsoft Windows Server 2003 SP1, when used with:
    • Microsoft Windows Server 2003, Standard x64 Edition
    • Microsoft Windows Server 2003, Enterprise x64 Edition
    • Microsoft Windows Server 2003, Enterprise Edition for Itanium-based Systems

SYMPTOMS

On a computer that is running Microsoft Windows Server 2003 Service Pack 1 (SP1), a 32-bit process must create a thread as soon as there is a printing operation. If this process runs in a Windows on Windows 64 (WOW64) environment, the 4 megabytes (MB) of memory that maps in the user mode address space leaks during every printing operation. These leaks continue even after a printing thread successfully ends. Therefore, when the process runs out of the user mode address space, you may experience unexpected errors because of the memory allocation failure.

CAUSE

This problem occurs because the 4 MB of memory mapping is created in the user mode address space when a thread calls the CreateDC API for a print device. Then, this is mapped when the thread ends.
