Mount error(12): Cannot allocate memory

Problem

When mounting some windows samba drives, “mount error(12)” error can occurred. Problem is in windows samba server settings. Full linux error message:

mount error(12): Cannot allocate memory
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)

and error message in windows event log:

Source: srv
Event ID: 2017
Level: Error
The server was unable to allocate from the system nonpaged pool because the server reached the configured limit for nonpaged pool allocations.

Solution

Update following registry:

HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache = 1
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size = 3

After you update these values, restart your computer.
