We recently upgraded complete an upgrade to XenApp4.5, and are having issues that were not happening during our testing phase. Our servers are constantly rebooting to the bsod, and I checked the event logs and receive the following bug check.
The computer has rebooted from a bugcheck. The bugcheck was: 0x000000c2 (0x00000007, 0x0000121a, 0x00a40014, 0xbc2be398). A dump was saved in: C:\WINDOWS\Minidump\Mini102908-01.dmp.
I also see a bunch of these WDICA error that I listed below.

All the minidumps we analzed and we found that the below (vdtw30.dll) file is causing the issue. Citrix support recommends that we install rollup pack 3, but that has not been tested in our environment. I just wanted to see if anyone else out there has come across this problem, and been able to resolve it. Please let me know when you get a chance.
