Kernel memory dump files may not be generated on Windows Server 2008-based and Windows Vista SP1-based computers when system memory is larger than the size of the page file

Kernel memory dump files may not be generated on Windows Server 2008-based or Windows Vista Service Pack 1 (SP1)-based computers. This behavior occurs when more system memory (RAM) is installed than the maximum size that is set for the page file.

 

CAUSE

This behavior occurs to help prevent kernel memory dump files from being written to a page file where the memory dump file is larger than the page file. This behavior helps eliminate incomplete memory dump files. Additionally, this behavior does not imply that the memory dump file is complete or valid.

 

WORKAROUND

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To work around this behavior, modify the registry so that memory dump files are written even if the system memory size is larger than the maximum size that is set for the page file. To do this, follow these steps:

1. Click Start, type regedit in the Start Search box, and then click regedit in the Programs list.

If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

2. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\CrashControl

3. On the Edit menu, point to New, and then click DWORD Value.
4. Type IgnorePagefileSize, and then press ENTER.
5. Right-click IgnorePagefileSize, and then click Modify.
6. In the Value data box, type 1, and then click OK.
7. Exit Registry Editor.
