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
I am having the same issue as Novell2NT regarding the hung process
And the disabling of the SMBv2 and oplocks didnt help suprise suprise.

@Novell2NT, Rhys
I was seeing similar issues when my servers hung. Couldn't open/close processes or logon/off users, without killing the whole server. I've had KB976674_v3 running since last Friday morning and the issue hasn't occurred since. However as I've been burned on this a few times I'm slowly ramping up the number of users. Only had between 25-35 users per box since Friday, I'm looking to get more users on for the rest of this week.
My rdbss.sys version is 6.0.6002.22277, what are yours? Novell2NT, you mentioned Outlook. What version are you running? 2007 sp2 with some updates i presume?
My MS contact has told me this issue doesn't occur on Windows 2008 R2, if anyone fancies doing a rebuild? :)

Hi everybody
we need help,We have a farm of 15 servers running Server 2008 x64 with XenApp 5.0. We were experiencing server hangs and need to restart the servers almost everyday to fix the problem .
Can sombody who has gott a working Fix from Microsoft send it to us please.
Best Regards
Ziad
I am running
Rdbss.sys 6.0.6002.22277
I only have 3 users connected to my terminal server, it is dedicated to these users due to the applications they run.
I am running Office 2007 SP 2 with a few updates.
At present I dont think rebuilding is an option from my side but, rolling back to an old image (ghost etc) is looking like a viable option if I dont get this sorted by next week.
You need to be careful about requesting a private hotfix from someone if you are not sure that you have the same issue. We are experiencing multiple issues; a couple of which have very similar symptoms but different root causes. your best course of action is to get a crash dump to Microsoft for analysis so they can confirm what your issue is. We are still running v2 of 976674 and on average are still having 2 out of 13 servers hang per day.
On top of this we have the issue mentioned above where users get "Please wait for the system event notification service" on log off. this hangs their individual sessions but doesnt affect other users on the server. I have an open support call with Citrix for this one as it is caused by a couple of Citrix processes locking handles which causes explorer.exe to queue indefinitely (until the server is rebooted).
R2 does fix these issues but Citrix dont have an R2 supported release yet. The tech preview only came out yesterday for XenApp 6; public release is hopefully due at the end of Q1 next year.
one of the primary triggers for us appears to be users connecting to .pst files over the network (which is unsupported by MS); also roaming profiles and /or redirected folders, specifically writing to index.dat (all of which best practice, they just dont work particularly well on server 2008). the guys that mentioned always seeing outlook.exe running on the server but not in the users session, do your users connect to .pst files?
I have opened a case with Microsoft and will keep you updated with the outcome
Thanks

Sorry I did not get back to you sooner.
My rdbss.sys version is 6.0.6002.22182, MSOffice is sp2. Have you seen any processes that will not terminate?
Has anyone found a fix for these the following errors and Citrix \ TS grinding to a halt "A timeout (30000 milliseconds) was reached while waiting for a transaction response from the CryptSvc service.", Does anyone run Sophos AV?
we have also had a lot of problems regarding this. Citrix on 2008 (on xen). every day one of our customers' citrix servers became unresponsive.
Also there was a lot of 7011 in the app log, but after disableing NLA & NLS services they disappered - but still the same server symptoms.
the day before yesterday i finally applied kb974030 (NOT 976674), and since then no sevrer hang.
Still not sure, but a lot of pressure has been removed :-)

@Novell2NT
funny are mentioning office 2007. I came across a sweedish forum where they where discussing this excact issue.
one guy made a repair of his office 2007 and said that after that he had no issue on 5 servers. A couple of days later day another guy followed the same procedure and his reply was that all of his 15 servers were working like a charm now.
BUT - after I tryed it out - it didn't work for me, BUT I dont think we can pin this problem/behavior to ONE thing. for those of you who tryed the MS patch without luck, try the office repair. would't hurt

I had previously found the Office repair bog, this didnt work for me either, also I think one of the users on tha tblog has posted on this site looking for an answer.User name is Ziad I think
I am running into the same issues with our Farm on Physical servers. 2008 X64 Xenapp 5.0 talking to a 2008 file server. Any updates on this at all? We are opening a case with Citrix to start.
What is everyone's system specs?
I'm running a virtual enviroment and I increased the memory allocated to my Citrix VM's from 2 gigs to 3 gigs and I haven't had a crash in 2 weeks.
