Symptoms

Consider the following scenario:

  • You enable the following Group Policy setting on a computer that is running Windows Server 2008 Service Pack 2 (SP2) or Windows Vista Service Pack 2 (SP2):

    Computer Configuration\Windows Settings\Security Options\Shutdown: Clear virtual memory page file

  • You try to shut down the computer.

In this scenario, the computer may stop responding.

Cause

This issue occurs because of a system page table entry (PTE) leak.

When the shutdown process occurs, the Windows memory manager tries to zero out all the page files in a loop. In each cycle of the loop, the memory manager uses the same memory descriptor list (MDL) variable to zero out the page files. However, the reuse of the MDL causes a system PTE leak when a storage driver calls the MmGetSystemAddressForMdlSafe macro to map the MDL to the system space. Therefore, the system stops responding after a while.

Resolution
