Teleop isn't exactly in a loop. It's called by the Robot Main vi whenever the Driver Station sends new data, and if your Teleop code doesn't finish before the next data packet arrives you'll start tripping the communication watchdog. Putting a neverending loop inside Teleop is a sure way to break your code.

Can you post your Teleop.vi file? I'm curious what you've done that lets the robot work even with the collection of unthrottled and unterminated while loops you say you've put there.
