A kernel dump file is not analyzable on a computer that is running an x86-based edition of Windows Server 2008 or a 32-bit version of Windows Vista Service Pack 1

Consider the following scenario:

• You have a computer that is running an x86-based edition of Windows Server 2008 or a 32-bit version of Windows Vista Service Pack 1 (SP1).
• The computer is configured to generate a kernel memory dump.
• The computer is in Physical Address Extension (PAE) mode.
• You set the increaseuserva parameter to any value to specify the amount of user-mode virtual address space on the computer.
• Non-Maskable Interrupt (NMI) occurrs when the computer is under high stress.

In this scenario, the generated kernel dump file is not analyzable through debuggers. If you check the dump file by using the Dumpchk.exe tool, the tool reports that the file cannot read, and a "0x80004002" error is returned.

This problem occurs because the system does not include system page directory information in the dump file under a specific condition that is described in "Symptoms" section.
