[Ovmsdev] Can buses stop after some time

[Tom Parker]

I haven't had a chance to try to work out what is going on.

I can say that the second can interface doesn't work for very long 
before stopping. This manifests most obviously on my Leaf as a stopped 
odometer in the OVMS app. If you look at the metrics in the console then 
everything that comes from the Car CAN bus (ie the second CAN bus) has 
frozen.

The first CAN interface seems much more reliable, with SOC information 
from the EV bus being fairly reliably reported.

I haven't done the modification to make my 3.0 unit's GPS work so I 
haven't experienced the stolen detection.

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.
