Symptoms

Consider the following scenario:

  • You have a computer that is running Windows 8.1 or Windows Server 2012 R2.

  • The server has more than 512 gigabytes (GB) of installed memory.

  • You run an application for which a memory region greater than 512 gigabytes (GB) is stressed.


In this scenario, the server encounters a Stop error 0x1A in the nt!MiUpdateWsle function.

Note This problem is observed when the system performs data intensive operations by using Microsoft SQL Server or when you use a memory stress test tool.

Cause

This problem occurs because of an issue in virtual memory management in the operating system kernel.
