Hi James
Unfortunately we dont use Appsense. I just had a look at resource manager
report for a server that is currently set to 10000. There are very little
resources being used. I have 1 active user and a down session.

Angela,
Do you have an Appsense Performance Manager agent with an active policy
installed on these servers?

Hi
Yes, when the server reboots, all is working OK. Server isn't set to 10000 and
there are no down sessions. However, issue re-occurs after a few hours. Issue
is happening on random servers so I don't think its a WMI Issue (very unlikely
that WMI is broken on 6 different servers). Nothing has changed on our servers
either.
We have a custom Load Evaluator which we have been using for several years
without issue. It basically checks CPU, Memory and User Load. Load is
definitely not an issue as the servers only have 15 users on them when the
issue occurs whereas they normally have 40. I cannot easily check resources as
all GUI tools fail to load. Task Manager, Perfmon, Sysinternals Process
Explorer etc don't launch. Whats the best way to see what is happening with CPU
and Memory? Perhaps I can run the tool remotely? As a test should I change
all servers to the Adv evaluator?
Ive never had any issues with memory. Each server has 16GB RAM. In relation
to CPU, Ive had the occasional process go crazy but its never used all cores.
Servers have 2 x Quad core CPU's. Print Spooler and Antivirus all appears OK
in that the service is started but I'm working blind as I cannot see the
processes due to the tools not launching
Perfmon wont load so I cannot rell is perfmon counters are corrupt
We do have SCOM. How do I reload the MOF?. Would the MOF generate a ICA down
session? Every server that goes to 10000 has a down session so its definitely
causing the issue or is related..
Thanks
Ang

We notice wmi issues as well, this was do to MOM/SCOM. We had to reload the
mof's to fix it.

Hi,
I have had WMI issues also in the past and had to re-build WMI components as

did you check if your perfmon counter is corrupted ?

The server thinks it’s at full load. What’s the load evaluator assigned to it?
If Task Manager is not loading, it sounds like perhaps a CPU/memory utilisation
issue, which is effecting the
load evaluator, which is placing the server at full load.
So what’s the CPU and memory utilisation on the server? Could you have a rouge
service, such as antivirus causing
problems? What about the print spooler and Citrix print manager services?
Cheers,
Jeremy.

Hi,
You say that even a reboot doesn’t help ? Is that correct ?
I had an RDP session in a down state that was doing the same thing I had to
reset it via the Microsoft
Terminal Services Console and this resolved that issue.
It did take a few times and I think I deleted my admin user profile as well as
they don’t get deleted
like all our user ones.

Ronnie

Hi
This patch looks promising.. Only issue is I cannot find it.
http://support.citrix.com/article/CTX123956
This has been superseded by R07 patch which I dont want to install right now.
Im currently running R06.
Does anyone have hotfix PSE450R05W2K3026 that I can download for x86 systems?
Thanks

Check the nonpagepool memory usage in taskmgr. I have seen this usage spike
which was due to an ms
bug and XTE.exe. Good news there is a fix for it. 936655 I beleive the number
is

Hi
I think my issue is different. All user sessions on these servers lock up and
they end up calling the helpdesk to reset them.. I'm getting down sessions on
the same servers each day (even after a reboot).. I applied CTX112103 but it
didn't make any difference..
Any other ideas apart from rebuilding?
Thanks

Hi Angela,
This does ring a bell and I’m sure I have one server with this patch and made
no difference to me,
but the csrss.exe process wasn’t showing a high CPU usage for me.
It more just creating error in console Session Down state every few mins. It
only stopped users
connecting on the very odd ocasion

Hi Ronnie
Unfortunately rebuilding wont be an option for me.. Did you try:
http://support.microsoft.com/kb/934330
My entire farm will reboot tonight. If issue re-occurs then I might try this
patch..
Thanks

Hi Angela,
I get this from time to time, server doesn’t always report full load but
there’s always a session
down state, and a reboot usually clears.
I had a look at the following thread but never actually got to the bottom of
it. I am currently
rebuilding all my server to upgrade to Office 2010 and hoping that the rebuild
does the trick.
http://forums.citrix.com/message.jspa?messageID=1386285#1386285
It’s seems to be going well as all the new builds have not reports the issue,
but one of the pre
Office 2010 builds did yesterday.
Regards,
Ronnie

Hi
I have an issue on my XenApp 4.5 farm where 4 servers are reporting Server load
10000. I tried to RDP to the servers and launch Task Manager. Unfortunately
this doesn't load on any of the 4 servers. I tried to use Process Explorer
from Sysinternals tools
but that also didn't load. What I did notice though was all 4 servers had a
session in a down state which I couldn't reset. It simply came back each time.
Error.jpg attached showing issue. I don't believe Im having a resource issue
but I cannot be 100% sure.
I tried to change my Load Evaluator from Advanced to Default as a test but this
made no difference. Also tried to clear some sessions but load didn't change,
still set to 10000.
Can anyone suggest how I can troubleshoot this 10000 Load issue without
rebooting server? FYI I do reboot my servers nightly but this issue has
happened a few times now. Also is there a way/tool to check system resources
when Task Manager doesn't work?
Thanks
Ang
