High usage on non paged memory pool / clustered system

August 28, 2007

Dear all,

I am suffering with high usage of non paged memory pool on my

clustered servers running on Windows Server 2003 Server R2 Enterprise

SP2. The typical usage is 100 - 110 MB. The memory pool tag MmCm is

using 50 MB of NPP.

Let's describe my setup.

I have 3-node cluster consisting of 2 HP DL 380 G5 servers and one

virtual server on VMware (this server acts as an arbiter in MNS MSCS

cluster). Both servers has 4 GB of physical RAM installed. Both

servers is using /3GB /PAE /USERVA=3030 boot.ini parameters specified.

I have clustered Microsoft Exchange 2003 Server Enteprise with SP2

running on one one. The second node has file server share clustered

resources, IIS clustered resource, DHCP and WINS clustered resource.

I have the Altiris Client Deploynment sw installed, backups are going

through Data Protector 6, we are using Mcafee Viruscan Enterprise

8.0.0. Note that I tried to stop all these services (DP, MCafee,

Altiris), without freeing any NPP memory.

Note that I have set the SystemPages registry setting to the value

50000, instead of recommended value of 0. When I tried setting it to

the 0, I ran out of free PTE's very soon.

Sometimes I encounter strange behaviour (for example of IIS service -

I had to set it to use aggressive memory allocation (not to refuse

connection when the free NPP fall bellow 20 MB, now it is t 8 MB), and

cluster service is reporting that the file share resource failed with

error 64 sometimes. I suspect the low resources symptom - low free NPP

(non paged pool). Maybe I have to remove the /3GB and /USERVA switches

from boot.ini at the file server cluster node, however, I don't know

if it will not run me in other problems related to different cluster

node config. I am not sure here.

How can I figure out, what driver/sw is allocating so much of NPP

memory? And what is best practice for configuring the boot.ini (can be

different among cluster nodes) ?

Just for clarify: I have cca 1000 users/mailboxes, typicaly 400-500

SMB/MAPI sessions concurrent.

Thanks for helping in advance, and bellow attaching the PoolMon

Re: High usage on non paged memory pool / clustered system

Hello,

==>Exchange does not support the PAE. You would remove it:

Use of the /3GB switch in Exchange Server 2003 on a Windows Server

2003-based system

http://support.microsoft.com/kb/823440/en-us

Because Exchange Server uses the /3GB switch as it scales up, the Exchange

Server computer cannot efficiently use more than 4 GB of RAM. Exchange

Server does not support instancing, Physical Address Extension (PAE), or

Address Windowing Extensions (AWE).

==>The Same for your Filer:

http://support.microsoft.com/kb/317249/en-us

Heavily stressed file servers should not use /3gb switch. The /PAE switch

alone will not cause any issue.

However, I found in one MS article, that this was true (remove /PAE)

in the past, now it is recommended (or supported), running Exchange

2003 on PAE kernel. For the file server, I think it is right to

remove /3GB, altough I still don't know whether I can have different

boot.ini configuration for the cluster nodes (one running exchange - /

3GB, one running file server services - without /3GB). What about

that?

My second question was, how can I determine, which process is using so

much of Non Paged Memory Pool, I can see only MmCm tag is using 50 MB

of it, but I don't know exactly the preocess name calling this

mechanism of allocation contigouous block of NPP memory.

Maybe I can try to set /USERVA switch to some other value to get some

MB of NPP?

Re: High usage on non paged memory pool / clustered system

For exchange, as stated in the KB:

Exchange Server does not support instancing, Physical Address Extension

(PAE), or

Address Windowing Extensions (AWE).

=>remove the /PAE on exchange

PAE is useful if you have more than 4G and application that can use it (like

SQL).

You would remove PAE on both node, it's useless for you.

You can have many entries in the boot.ini, choose your default. You will be

able to change manually at each boot.

Start by removing the /PAE on exchange and /3G /PAE on the filer.

This would correct your issue at the root.

ProcessExplorer would be helpful:
