Internal Server Error because app won't quit

Looks like what I have been seeing.

I have this mail form program. Rather simple, just the LR example, a TextArea, a couple TextFields and a button. Running just fine since November 9.

The live demo of RubberViewsWE has been currently running since 00:50. I doubt very much there has been a continuous flow of visitors since.

To me what counts in the end is that the program is accessible to users.
