Hmm, after looking at the picture, there doesn't seem to be any on the 4 slot version. There is a way to check the CPU usage on the cRIO when you are plugged into it, but I can't remember off of the top of my head how to do it. That would be another way to verify that the 100% usage is the problem. IF that does turn out to be the problem then you probably need to put some delays in some of your loops.
