Calculating Max Page Pool Size

[Guest idflyfish@gmail.com]

Hello,

 

I am getting the infamous "Operating system error

1450(Insufficient system resources exist to complete the requested

service.)" error on a Windows 2003 Enterprise server with 8GB of

memory and /3gb /PAE switches. I setup a counter in MOM to measure

Pool Paged Bytes and it looks like we start running into issues when

Pool Paged Byes reachs about 120MB. The syptoms range from sql backup

failures to profiles not loading when techs trying adn RDP to the box

(due to the fact windows cant load ntuser.dat). I have read some

articles on how to increase the size of this pool but I would like to

find out what our limit is now before I start making changes. Can

anyone help?

I assume that you are referring to PagedPoolSize at:

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session

Manager\Memory Management

 

From doing a bit of searching and reading I have found that according

to Microsoft:

 

• If you are running /3GB and /PAE together, do not set this setting

without extensive testing and before you establish exactly how many

system PTES you must have in your environment. You will probably see

values in the range of 10,000-20,000 free. Use the articles to configure

paged pool memory but never drop below 10,000 free system PTEs. Do not

set this to any other value if you are using the /3GB switch. The only

supported values are 0, 0A000000, and FFFFFFFF.

Maybe you should contact Microsoft for further assistance.
