[Ovmsdev] Can buses stop after some time

Hi all, I synced up with master about a week ago and since then I've seen both can busses stop working. I still see the 12v battery metric changing, but everything that comes from the car stops. Rebooting the module with "module reset" does not seem to fix it, while make app-flash monitor does fix it. I haven't tried make monitor on it's own. Is anyone else seeing behavior like this? Sorry for the vague bug report. I'll spend some time later this weekend to try to gather more information.
