Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Server 2008 or Windows Vista.

  • You run some WMI Query Language (WQL) queries by using the Windows Remote Management (WinRM) scripting API or through the Winrm command-line tool on the computer.

In this scenario, the memory usage of the Windows Remote Management service keeps increasing. Over time, the available memory on the computer is used up. All applications or services on the computer stop responding or crash because of insufficient memory resource.

Cause

The issue occurs because the Windows Remote Management service does not call the destructor functions of some derived classes correctly, and this causes a memory leak issue.

Windows Vista and Windows Server 2008 file information notes

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.0.6000.16xxx

    Windows Vista

    RTM

    GDR

    6.0.6000.20xxx

    Windows Vista

    RTM

    LDR

    6.0.6001.18xxx

    Windows Vista SP1 and Windows Server 2008 SP1

    SP1

    GDR

    6.0.6001.22xxx

    Windows Vista SP1 and Windows Server 2008 SP1

    SP1

    LDR

    6.0.6002.18xxx

    Windows Vista SP2 and Windows Server 2008 SP2

    SP2

    GDR

    6.0.6002.22xxx

    Windows Vista SP2 and Windows Server 2008 SP2

    SP2

    LDR

  • Service Pack 1 is integrated into the original release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
