Hi,
We are encountering some strange problems with a XenApp 5.0 farm that runs on Windows Server 2008 SP2. The farm consist out of 2 XenApp 5.0 servers with a single server that hosts the web interface. Underneath the OS we run VMware ESX 3.5 update 4. Usually everything runs ok but's the performance is very bad. The XenApp servers have 2 vCPU's and 4GB memory. We use roaming profile with folder redirection for some folders.
WE publish the desktop to our users so we installed all application on the 2 servers en use NTFS permissions for application access.
The problems:- Performance is not ok. When users are typing in Word (Office 2007) or other applications the characters will display with some latency, not always it happens sometimes.
- One server becomes unresponsive. Application that are allready started work very slow. New application which are started from the Start Menu won't appear. After some minutes the server goes further and all application will appear. It looks like the server is sleeping for a while. When that happens the System log shows the following errors:
7011 - A timeout (30000 miliseconds) was reached while waiting for a transaction response from the RasMan service. 7011 - A timeout (30000 miliseconds) was reached while waiting for a transaction response from the NlaSvc service. 7011 - A timeout (30000 miliseconds) was reached while waiting for a transaction response from the CryptSvc service. 10010 - The server {AAC1009F-AB33-48F9-9A21-7F5B88426A2E} did not register with DCOM within the required timeout.
Kind regards,
Onno van den Berg
Hi guys, I dont want to rain on anyones parade but I have had 3 servers hang since last night and I'm running v2 of the Hotfix. I have a crash dump from one of them and will get that to MS today.
I'll let you know what comes of it.
Cheers, Dan
I have had KB976674 v1 installed on 85 production servers for 72 hours without significant issue. One of the servers exhibited symptoms similar to the original issue (NLASvc timeout) but was otherwise functional despite the service timeouts in the event log.
KB976674v2 is on all production systems since Friday. Yesterday two servers with KB976674v2 crashed but at least left a memory dump. The BSOD was caused by TCPIP.SYS and a Hotfix was instantly provided (KB976035).
In addition I just received v3 of KB976674 since v2 is withdrawn. My version is 32bit, so please no request for the 64bit version.
I will install both KB976035 and KB976674v3 tonight on the production systems since the install on the test system went smooth.
RegardsStephan
I got the 64bit version of KB976674_v3 today so I'm going to apply it tonight. Will post how I get on with it tomorrow or Friday. I had been given a different hotfix up to now, a KB974030.
Regards,Ian
Just as an aside, does anyone know if this issue occurs on Windows 2008 R2?
Cheers,Ian
I can confirm that KB976674v2 does not help.
I've also tried the workaround from KB 972596 (disabled oplocks on all XenApp servers and fileserver) but this makes no difference either.
I have mentioned this before, but no one responded to what I think I am seeing when the freezing occurs.
I have been logging all my users out at night for a long time now, and all the time that the server freezes up, it is directly due to a stuck application, that cannot be killed. Most of the time it will be Outlook.
I will see someone with an Outlook process running, but when I take over their session, Outlook is not up and running and if I try to end the process it will not end. I know at this point that the server will freeze as soon as I log someone out or if I disconnect anyone from the server.
I have seen the same occurrence with Excel and QB, but most of the time it is Outlook (2007). Can anyone confirm this behavior?
I am seeing the same issue as Novell2NT, (we do not force our users to log out overnight, but we get a support call to say that a users session is not responding, if we look at the process's running Outlook is there but not running on the desktop. If we try to end the process or log the user off, thats when the calls flood in all users are now not working on the particular server, only option now is a reboot, as we can't log users off and can not log off the server ourselves or even get any apps to start up for trouble shooting.
The only difference for me is i am not using XenApp (these are standard 2008 sp2 Terminal servers 32bit, running either enterprise edition or standard edition. With office 2007 and some other apps.
Hotfix KB976674v3 appears to solve the problems on my 64-bit servers, they all ran more than 24 hours without freezing/crashing.
We haven't had any freezing for more than a week now. For us KB976674v3 seems to be solution as well. Since we had freeze free periodes of three days in a row before that, I'm some what sure this case is closed.
Unfortunately we encountered 3 crashes related to TCP Chimney Offloading caused by a faulty Citrix driver. But this is another story.
we have the same problem with our terminalservers 2008
could you send me the patch KB976674v3 ?
thanx!!
Regards Patrick
Hi
We are having the same problem on our Windows 2008 sp2 x64 server.
I have applied KB976674v3, which didnt seem to resolve the issue, we had a crash 14 hours later.By the way does anyone have the file versions of the following files, where their server is working.The file versions listed are what I currently have, these are different to what a Microsoft representative told me they would be, but when looking in the cab file the rdbss.sys file seems to be at the right version
Rdbss.sys 6.0.6002.22277Ntoskrnl.exe 6.0.6002.22248
I have subsequently disabled SMBv2 and oplocks, and am holding thumbs that this works, but doubt it.
Any other ideas.
Regards Rhys
Hi guys,
We installed KB972596 and didn't experience any more hangs. We did start to experience crashes which Microsoft said was caused by our BASP.sys NIC teaming drivers for our Broadcom NICs. After updating the BASP driver we haven't experienced a crash. Hope this helps someone. I'm still keeping my eye on the public release of KB976674 just in case.
Jon
Thanks for the info Jon. I do not think I have seen you on here before, can you give us the specifics of your case? Several of us have tried KB972596 without any luck. Are you on x64 Windows 2008, what kind of problems were you experiencing ?

Hi Novell2NT,
We have a farm of 8 servers running Server 2008 x64 with XenApp 5.0. We were experiencing server hangs where a user would log off of their Citrix session, but would not fully log off of the server. Typically I would see they were still running taskeng.exe. If the user tried to log back in, their Citrix session would be directed back to that hung session and they would see "Waiting for System Event Notification Service" indefinitely. I couldn't kill the process, and over a short period of time the server would become completely unresponsive to the point that a hard reboot needed done. KB972596 seemed to solve it, however we had other issues with NIC drivers as I described.
