We've seen that at several occasions. Usually, it's only the Web service which is stopping. As for us, we haven't identify what causes this. This is something we had at a client site.

There are some few basic things you can do. Make sure you have the latest patches and keep watching the event log. Maybe you'll find a pattern which you can associate. There might also be an external service or another application which relates to all this. As for us, when we had this, as far as I can remember, no identifier has been found. I think they are still looking for find the reason. I remember, to proceed by elimination, we remove almost all the components and were running with minimum configuration. It was still occuring after.
