I have issues with 2 XenApp servers in my lab. When I work some time on it (half a day, only 1 user), it freezes suddenly (both systems have the same behaviour). I can't do anything but shutdown the vm/xenapp-server (console is black). CPU & MEM are full, don't know what is happening. Events happened especially at 27 August.
Here are logs of XenApp1 server as well as some screenshots:
