Safe shutdown function takes 1-2 minutes to shutdown

[Sailoog]

(Sailoog I posted this in the wrong thread indeed  , but already deleted it)

I installed Maiana again and the error the ~1.5 minutes shutdown time is back.

Using htop I can see that the only process that eventually spikes above 10% is avnav_server.py.

SignalK server stays somewhere between 4%-7%, which i think is quite normal. Average CPU usage is below 15%

I can not reproduce that but I will investigate further.

Anyway, we would only be concerned if the shutdown sequence does not complete.

These "long" shutdowns are the reason we chose this method, other supercapacitor based solutions would not suffice and why use extra batteries if your boat already has a big one?
