I've had this error a couple of times, but never as bad as you. However, it seems to be an XBOX related issue, more than an IL2 problem. Still Anton or a developer might have an answer for it. There is a developer's forum for IL2 as well, you should try posting it there too. Here's the link:

My advice would be to contact Microsoft, and in a worst case scenario see if you can return it to your dealer to get a new one.
