Hey Paul,

Maybe I'm being a troll but I emailed you privately in regards to a thread you 
started about a profile cleanup script and never heard back from you (seems 
like it's pretty easy to copy/paste into an email was my thought).  I had 
shared what little I had to contribute and hoped that helped you find a 
solution and also might improve my solution at the same time.  That's the point 
of these lists right?  They're ideally a two way street, sharing of 
information, kum-by-ya and all??  Of course the level of obligation to a list 
is exactly zero so whatever.
However if you were expecting a solution from someone else on the list and were 
hinting at disappointment with a statement like this:

"Two replies from the most knowledgeable guys I know and you've never seen this 
issue before? :) "

Then I really don't feel bad for you.  :)

Cheers,


Dan Dill

Now now, Not all of us can run XA 6.5 with 2008 R2..  As we have apps that 
aren't compatible :)

It's still better then XA 4.5

Yeah, understandable. Most places don't run Windows 2008.  Those organizations 
that did go Windows 2008 have since migrated to Windows 2008 R2 w/ XenApp 6.5.  
Hint, Hint, Wink Wink.

This issue is occurring on a Xenapp Presentation Server Running..

Running XA 5.0  (Platinum Edition)

The latest released Rollup pack for Win2008 For Xenapp 5.0 is Rolloup 01

Unless I'm missing something completely :)

I see a Rollup 07 for Xenapp 4.5  but we're not running that..

Why are you just on R01 when R07 has been out for a good while?  Or did you 
mean XA 6.5 Platinum on 2008 R2?

Subject: [THIN] Urgent Issue -- "Please Wait for Local Session Manager"

Let me preface this with the following information

Environment:

XA 5 Platinum
Rollup 01 applied (and a couple post R01 Printing related Hotfixes)
Citrix Profile Management 4 (Although all users are logging in anonymously on 
the servers this is impacting)

Presentation Servers running:  Windows Server 2008 Enterprise Edition x64bit
Occurs on both Physical and Virtual machines
Only occurring in "One" of our 2 Datacenters

MS KB2661001 already applied and issue still occurring.

When launching a Published app or attempting to RDP against an affected server 
the user receives the message "Please Wait for Local Session Manager"  and it 
will just sit there. Sometimes eventually logging the user in ~15 minutes later 
but more frequently it just sits forever
The only "Fix" is to either reboot the server, or forcefully terminate IMA and 
restart.

It should be noted I had a memory dump sent to  MS for analysis what they came 
back with is the following:

The analysis from the MS Debugging team shows that LSM (Local session manager) 
is blocked on a chain of blocked threads that leads up to Citrix's ImaSrv 
service. In this process there request processing threads are blocked on a lock 
that is owned by another thread within ImaSrv and this lock owning thread has 
been waiting from past ~4 minutes to receive acknowledgement of a RPC bind 
packet that it has sent to 
mydomaincontroller.domain.com<http://mydomaincontroller.domain.com> over TCP 
transport at port 49156. The client will wait for a timeout period of ~15 
minutes. As such I don't see if this request is blocked in the local network 
stack, but appears that the DC has not been responding. IMASrv has issued 
DsCrackNames on "MYDOMAIN\UserID1234" to convert the directory service object 
names from one format to another. However what we are interested here is to 
understand why RPC bind didn't complete.


Forcefully terminating IMA and restarting it, "Fixes" the error for the time 
being. But if ANYONE has seen this issue before and has any suggestions I would 
welcome them.
I have a case open with Citrix, and they're analyzing the memory dump as well, 
but I thought I would ask the brain trust to see if they had any suggestions. :)


This is a new one on me.  Any assistance is welcome!
