Applications freeze when printing

Citrix users experience slow performance and freezing sessions

Since about this monday we have had severe problems with our Citrix environment. The symptoms are users are experiencing very slow connections from time to time and from user to user, today we had problems with users are unable to print (although I haven´t had time to investigate it further). The sessions would freeze after a short time. This happens even if users ends up on another XenApp server. So it follows the user/users who are affected and not the XenApp-server they end up on.

Ok so here is the environment:

12 XenApp servers on IBM blades (not vmware). Windows 2003 32-bit servers. XenApp 4.5. 1 Web Interface (vmware) 1 data store/SQL server (vmware) 1 provisioning server which provisions the 12 XenApp servers above (we had 2 provisioningservers up to a couple a weeks ago when we saw that XenApp servers provisioned from 1 provisioning server died almost daily).

We publish applications to different "sites" and it began this monday with users in one site complaining about slow performance and one user had problems with the applications just crashes. There was a technician at the site who said it crashed immediately and a window stating "citrix has crashed" (or simila) appeared. It didn´t help to reinstall Citrix online plugin 11.2 as we use, even after clearing out the users profile files related to citrix. Others tried to use citrix on his computer but it didn´t work. His computer got reinstalled this wednesday and it worked good after that.

Now today all * * broke loose. 3 people in another site (we do NOT manage the sites, they are external customers so we dont have any control over their computers) complained about the citrix window just become blank and sometimes just black. I asked them to try some other application but it was the same error on all applications, not just the one they mainly use. Then after 4 hours the problems went away for a while. Then they come back again! And in the midst of all this they all were unable to print anything. I have worked with our citrix environment for 3 years and have never encountered a printingproblem so I guess it must be connected to this error as well. Only this "site" had printing issues, no one else.

A lot of information and vague info but if anyone has any tip I would appreciate it extremely much!
