Kevin:

Please take a look on the memory management registry keys under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management. Especially, look for "SystemPages" dword value. Default should be 0x0, if this is set this to another value, it may be the root cause of this condition on your system (technet.microsoft.com/.../cc786402(WS.10).aspx).

Hello…wanted to clarify one thing about too much physical memory…you have mentioned that too much memory can cause low system page table entries problem , so wanted to know how efficient is it to reduce physical memory.

Also I understand that it’s not only physical memory but there could other heavy consumer of pte’s like video card.

In such we could enable this registry entry to find who is the highest consumer or not releasing the pte. http://support.microsoft.com/kb/256004

But I wanted to get a general ideal about how efficiently pte stand at a high number on machines with huge amount of physical memory.

Specially in scenario where there is huge amount of physical memory on data centers edition on x86 platform).

Hope I am clear in mentioning my questions.
