Symptoms

Consider the following scenario:

  • You install Internet Information Services (IIS) 7.5 on a computer that is running one of the following operating systems:

    • Windows Vista

    • Windows Server 2008

    • Windows 7

    • Windows Server 2008 R2

  • You run a Windows script to connect to the Windows Management Instrumentation (WMI) WebAdministration namespace.
    For example, you run the following VBScript script:

    Set oIIS = GetObject("winmgmts:root\WebAdministration")
    Set oSite = oIIS.Get("Site.Name='Default Web Site'")
    WScript.Echo "Retrieved an instance of Site "
    WScript.Echo " Name: " & oSite.Name
    WScript.Echo " ID: " & oSite.ID
    Set objInParam = oSite.Methods_("GetState"). _
    inParameters.SpawnInstance_()
    For i = 0 to 10000
    Set objOutParams = oIIS.ExecMethod("Site.Name='Default Web Site'", "GetState", objInParam)
    Wscript.Echo "Out Parameters: "
    Wscript.Echo "ReturnValue: " & objOutParams.ReturnValue
    WScript.Echo "LoopCount : " & i
    objOutParams = NIL
    Wscript.Echo "NIL is " & objOutParams

    Next
    oSite.Stop

In this scenario, a memory leak may occur in the WmiPrvSe.exe process.
