[THIN] Re: Insufficient system resources

Hi Jeremy
                I installed KB943545 last night. I will make changes to 
registry as suggested tonight. Just to make sure:-

Change value for "PagedPoolSize" from dword:zero to dword:ffffffff ?

Create "PoolUsageMaximum" with value dword:0000003c ?

Am I right

Thanks
Thomas

This worked really well for me.  I implemented the fix and the servers have 
been behaving a lot better since.
Thanks again,

Hi Thomas,

Yep, it applies to all server roles, Terminal Servers included. Microsoft will 
tell you that setting these values should be considered as a best practice, 
especially for busy servers. The optimum percentage for trimming will vary, but 
the default recommended setting (60%) is a good place to start. High CPU 
utilization could be a roll on effect from a number of different things, such 
as Disk I/O, etc, not just memory inefficiencies. But check out a couple of my 
articles for starters...

http://www.jhouseconsulting.com/index.php/blog/2008/05/15/microsoft-windows-2003-post-sp2-hotfixes/

If CPU usage continues to be an issue, use a 3rd Party product like AppSense to 
control the "issue". Or even try out the FREE ThreadMaster.

Cheers,
Jeremy.

Hi Jeremy
                I was watching this thread and I am wondering whether this will 
apply to terminal service as well. I checked my terminal server (Windows 2003 
standard edition sp2), "PagePoolSize"=dword:0 and do not have "PoolUageMaximum".

                The server is performing not very well (high CPU utilization)

Nah....run up  perfmon and have a look at pagefile usage. On a heavily utilized 
server I have only ever seen 30 - 40% max. To me it sounds like the paged pool 
memory is not coping.

As per Microsoft TechNet article KB312362. By default, the Memory Manager tries 
to trim allocated paged pool memory when the system reaches 80 percent of the 
total paged pool. Depending on the system configuration, a possible maximum 
paged pool memory on a computer can be 343MB (Windows 2003 Standard) and 80 
percent of this number is 274MB. If the Memory Manager is unable to trim fast 
enough to keep up with the demand, then you may receive event ID 2020 (The 
server was unable to allocate from the system paged pool because the pool was 
empty). But that is just one symptom.

By tuning the Memory Manager to start the trimming process earlier (for 
example, when it reaches 60 percent), it would be possible to keep up with the 
paged pool demand during sudden peak usage, and avoid running out of paged pool 
memory.

60% is the recommended baseline to start at.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory 
Management]
"PagedPoolSize"=dword:ffffffff
"PoolUsageMaximum"=dword:0000003c

Cheers.

The profile permissions seem fine and everything works fine once the user load 
goes down.
I think the problem may be that the page file is only 4GB and the servers has 
4GB of RAM.
a 4GB page file is the limit on regular Windows 2003 SP2.
I know that R2 does not have this limit.  So my question is:

Is there a way to go above a 4GB page file on Windows 2003?
Is there an upgrade path from Windows 2003 to Windows 2003 R2?  or is this a 
free upgrade?  Technically it is the same OS with some improvements.

Thanks,

Subject: [THIN] Insufficient system resources
Hi all,

Lately users have been getting this error when they attempt to log on to our PS 
4.0 Citris servers.

Description:
Windows cannot load the user's profile but has logged you on with the default 
profile for the system.
 DETAIL - Insufficient system resources exist to complete the requested service.

And since I don't allow local profiles, they can't log in.

I look in task manager and the system resources do not seem to be overutilized. 
 CPU is around 40 to 60%.
Memory usage seems normal.
I have Hotfix rollup 4 on the servers, no other patches.
Logging off a few users seems to correct the problem.

Any idea what else I should look for?

Currently, I have an idle timeout period of 3 hours, am I being too good?

Thanks,
