I may be misunderstanding GAE, but isn't the reporter's 'StayUp' servlet a minimal test case? Without any dependence on other datastores or processes, it seems to be showing that something is seriously amiss when handling trivial requests. It's like a demo "Hello World" app... that stops working in a certain time range each day.
