No Memory.dmp File Created with RAM Above 1.7 GB

ID: Q173277

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server version 4.0, Terminal Server Edition
Microsoft Windows 2000

SYMPTOMS

In systems where RAM exceeds 1.7 GB, Memory.dmp files are not generated even though a sufficient pagefile (RAM + 11 MB) is available on the boot drive.

Additionally, if larger Memory.dmp file images are produced (by applying hotfixes referenced below), several support utilities should be updated to read the larger Memory.dmp images. Without these updated files for dumpchk, dumpexam, i386kd (or alphakd, mip, ppc) and windbg the following error message is generated:

Could not initialize crash dump file <path to dumpfile>.

CAUSE

Several causes were isolated related to mapping views of very large memory images.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, please see the following article in the Microsoft Knowledge Base:

Ntoskrnl.exe (or Ntkrnlmp.exe) and Savedump.exe are used to produce larger Memory.dmp files.

Dumpchk.exe and Dumpexam.exe are used to verify the larger Memory.dmp files.

STATUS

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
