Description

  • How to create a Full Crash Dump
  • At times, Technical Support may require a Full Crash Dump from a device to fully identify the root cause of a system crash
  • The following instructions will assist in generating this file

Environment

  • N-able N-central
  • N-sight RMM
  • N-able Backup
  • Risk Intelligence
  • Take Control

Solution

  1. Check the page file settings and adjust as necessary:
    1. Open the Control Panel and double-click on System (alternate method: right-click on My Computer)
    2. Select the Advanced tab
    3. Under " Performance" click on the Settings button
    4. Select the Advanced tab
    5. Click on the Change button
    6. Check that the page file on the boot drive is large enough to store the entire contents of memory plus one megabyte.
      • For example if the system has 1 gigabyte of memory (1024 megabytes) the "Initial size" field should be at least 1025 (This is actually memory size plus 1 meg.)
    7. Adjust the page file size if necessary
    8. Click the Set button
    9. Click OK
    10. Dismiss any "reboot required" dialog boxes by selecting reboot later
    11. Click OK
    12. Leave the System Properties window open and proceed to the next section
  2. Enable Complete Memory Dump
    1. Under "Startup and Recovery" click the Settings button
    2. Under "Write debugging information" select Complete memory dump from the drop down list box.
    3. Check the box Overwrite any existing file
    4. Click OK
    5. A message about pagefile requirements may be displayed -- if so, click Yes
    6. Click OK
  3. Reproduce the issue, causing the crash to occur
  4. During bootup after the crash, the dump file will be generated
    • Please allow this to continue or it may be corrupt or truncated prematurely
  5. Gather the MEMORY.dmp file from C:\Windows\
  6. Place this file into a zip
  7. Upload the resulting zip file to https://supportfiles.logicnow.com/data/public/customer_uploads.php
