PoolMon: MmCm tag - High nonpaged memory pool usage

[Guest martin.necas@gmail.com]

Dear all,

 

I am troubleshooting an server with high nonpaged memory pool usage.

It is an HP Proliant DL380 G5 server with 4 GB of physical RAM. I am

running the Microsoft Exchange Server 2003, therefore I am have to run

under /3GB boot.ini switch. So I am limited do ~125 MB of nonpaged

memory pool maximum. I am running at about 105 MB of used nonpaged

memory pool, I worry about the stability.

 

When I start the PoolMon, it shows that 40 MB of nonpaged pool is

using the MmCm tag, which belongs to the nt!mm driver and "Calls made

to MmAllocateContiguousMemory". This is the biggest usage, all others

are about 1-2 MB. How can I determine, which driver(s) is allocating

so much memory? Or are there any chance to get this kind of

information?

 

Thank all
