Yep, that's probably exactly what's happening, I've had it happen too. And the solution is the ping that he proposes. So if that was the problem, the ping is resetting the session cookie every 60 seconds and the problem should go away. One thing I would add is a logging feature that tracks how many times this actually happens (is happening) so they have metrics to back up any decision in the future.
