Anything in the System Logs when that happens?
I haven't seen that before (or heard of it) that I can recall and I've worked with hundreds of installs in all kinds of situations.
2.0.2 will be out before too long here so it's probably best to hold off on reporting such a thing until trying it with the latest version (once it's out).
It seems like dnsmasq died at 03:54:27
It restarted at 08:33:16, that's the time I entered the webconfigurator and just saved the configuration as it was (no changes made).
Does this give any insight to you?
I've got this:
