Symptoms

On a computer that is running Windows Server 2008, Windows Vista, Windows 7 or Windows Server 2008 R2, you may receive the following Stop error when the computer is under heavy load.
Stop 0x00000050 (parameter1, parameter2, parameter3, parameter4)
PAGE_FAULT_IN_NONPAGED_AREA
Note
  • The parameters in this Stop error message may vary, depending on the configuration of the computer.
  • Not all "0x00000050" Stop error messages are caused by this problem.
Note This Stop error occurs in the Srv.sys driver that is used by the Server service. This issue may occur when users access a shared resource on the computer remotely.

Cause

This issue occurs because of a race condition in Server service driver (Srv.sys). The race condition occurs when the Server service driver checks a structure and does not have the expected spin lock. This behavior causes an access violation exception in the Server service driver. Therefore, the operating system triggers the Stop error.

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.

    VersionProductSR_LevelService branch
    6.0.600 1 . 22xxxWindows Vista and Windows Server 2008SP1LDR
    6.0.600 2 . 22xxxWindows Vista and Windows Server 2008SP2LDR
  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxx version number.
  • 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 files and MANIFEST files, and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
