Version: 3.1.0.M3 - stops working after a couple of hours

Ok, the reason was something else then the log entries. When I power on my second Fritzbox, the AVM Fritzbox Connection brakes.

The problem is documented here:

I simply disabled my second Fritzbox, as I do not need it in Openhab. Now, everything runs fine.

Thanks anyway for all the support!
