Symptoms

Consider the following scenario:

  • You access some shared files from a computer that is running Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2.
  • The computer is working under a heavy stress situation.
  • The connection to these shared files is lost. For example, you log off the computer.

In this scenario, the computer may restart unexpectedly. Additionally, you receive a Stop error message that resembles the following:

Note

STOP: 0x0000007F (0x0000008, parameter2 , parameter3 , parameter4 )
UNEXPECTED_KERNEL_MODE_TRAP

Notes

  • The parameters of this Stop error message vary, depending on the configuration of the computer.
  • Not all "0x0000007F" Stop errors are caused by this issue.

Cause

This issue occurs because the Redirected Driver Buffering SubSystem (Rdbss.sys) driver causes an infinite loop that exhausts the stack space of a thread. Therefore, you receive the Stop error message.

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.

    Version Product SR_Level Service branch
    6.0.600
    1.
    22xxx    		 Windows Vista and Windows Server 2008 SP1 LDR
    6.0.600
    2.
    22xxx    		 Windows Vista and Windows Server 2008 SP2 LDR

  • 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.
