Error: The server was unable to allocate from the system nonpaged pool because the server has reached the configured limit for nonpaged pool allocations

Article Number: 
131

Problem:

After several days of backing up clients to a windows 7 machine acting as a BDR, the clients are no longer able to connect. Rebooting the BDR resolves the issue for a few days. 

Looking in the System Event viewer the following entry will be shown.

Error 2017

"The server was unable to allocate from the system nonpaged pool because the server has reached the configured limit for nonpaged pool allocations."

Cause:

Windows 7 is not designed to handle the large traffic generated by backing up multiple clients. 

Resolution:

The following registry keys can be adjusted to help windows 7 manage the high traffic.

Set the following registry key to '1′ (default value is 0 - zero):

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache

Set the following registry entry to '3' (default value is 1):

HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size

A restart is required after making the changes.

Windows 7 should not be used as a backup destination.  Windows 7 is a workstation OS and not intended by Microsoft to be used as a file server.
