Citrix Xenapp 6 locks up on server 2008 R2 Sp1

Is there any perceivable pattern to it? Can you track it to when a particular user is doing something, say?

Aything in the event logs?

It might be worthwhile monitoring with performance monitor to see if anything ramps up just prior to it happening.

It's been a long time since printer drivers were really able to cause this kind of behaviour, but it might be worth checking through which you have installed on the server and update them to the latest available.

Any AV software that might be causing problems?

How is the network in general when it happens?

The servers aren't virtual are they? I've seen this behaviour when storage connectivity is lost.

The only thing I can tell to you - you are not alone :)

We can't contact Citrix, since we are only testing xenapp now and preparing it for production. Installing Xenapp 6.5 don't solve this prolem, it still occurs every 7-10 days.

Simplejack if you go through a partner, they should be able to raise a call on your behalf.

No pattern to it at all.  No printers installed on the server. Disabled the AV to see if that was the issue, no help.  Physical servers not virtual.  The network is great even when this happens it only causes problems with the citrix server only.

I have not tried that hotfix yet but will try it tonight afterhours since it requires a reboot.  Thank you very much for the suggestion.

You're welcome.

Do you have access to mycitrix to get it? If jot, as I'm a partner, if you use the hire me button in my profile I can get it for you.

I do have access, thank you very much thou!

I applied the hotfix late last night and will update this case as to if it has resolved the issue.

So it has been about a week now with no lock up.  Looks like that hotfix fixed it.  Amazing the Citrix Tech support didn't recommend it to us.  Thanks Again!!

My experience (as a partner) is it quite simply depends who you get to speak to. Some are somewhat better informed than others.

Glad I could help in some small way :-) Thank you for the points.
