DOCUMENT:Q173277 20-MAR-2002 [winnt] TITLE :No Memory.dmp File Created with RAM Above 1.7 GB PRODUCT :Microsoft Windows NT PROD/VER::4.0 OPER/SYS: KEYWORDS:kberrmsg kbtool kbWinNT400sp4fix kbOSWinNT400 kbOSWin2000 kbDSupport ====================================================================== ------------------------------------------------------------------------------- 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 NT Server, Enterprise Edition version 4.0 ------------------------------------------------------------------------------- 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 . 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: Q152734 How to Obtain the Latest Windows NT 4.0 Service Pack For your convenience, the English version of this post-SP3 hotfix has been posted to the following Internet location. However, Microsoft recommends that you install Windows NT 4.0 Service Pack 4 to correct this problem. ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT40/hotfixes-postSP3/2gcrash - 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. You may be able to work around this problem by limiting the maximum amount of RAM the system accesses to 1.7 GB or less. To do this, use the /MAXMEM= switch in the Boot.ini file. For more information, please see the following article in the Microsoft Knowledge Base: Q108393 MAXMEM Option in Windows NT BOOT.INI File 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.
