Thanks for the investigation. Increasing the checkpoint timeout is not a perfect science but at least it would work until a machine is able to be slower than the current limit reached, so I would be OK with your suggestion and raise the bar a bit more to prevent the race created by these extra checkpoints triggered because of the time. -- Michael
