What it sounds like you're describing is what we were experiencing earlier.. We were having a problem where the robot would respond to commands for about a second, then our programming laptop would lose connection to the C RIO, then it would get it back for a second, and so on. It turns out we had a loop without a delay in it, om nom noming all the processing time.

I don't know if there's a way to measure the CPU usage in windriver, but I'd suggest trying to find that or double-checking your code that you don't have anything too strenuous.
