Hi Bryan,

A very interesting post to say the least. I'm confused about some of the details however.

I attempted to follow the above instructions to find the total MmSt size and total PTE's and believe it worked.

What I don't understand is the size of MmSt reported seems to be abnormally high,

like in your example..

MmSt size : 502321952 bytes

That's close to 500MB! Which certainly can't correspond to the poolmon paged pool size corresponding to MmSt (unless your on x64 ?).

Could you please clarify what this size actually corresponds to ? And how we can track the size reported under paged pool in poolmon for the MmSt tag.

Hi,

The mmst tag is related to the pool paged memory, and PTE is related to nonpaged pool memory, if mmst tag is consuming lot of memory then the paged pool is not recycled, this could be most common in windows 2000, all you have to do is trim the memory by making an entry in the registry you can make it at 60%, so that after reaching the maximum memory the paged pool will be recycled
