You are amazing! I already had the feeling that I could be related to the MQTT-Broker… But that there are retained messages that cause the kernel panic - never thought about it.
Problem solved within seconds!
On the MQTT-Broker-Host I simple did the following:
sudo systemctl stop mosquitto.service
sudo rm /var/lib/mosquitto/mosquitto.db
sudo systemctl start mosquitto.service
That’s it! I flashed version 0.9.11 again an everything works like a charm.
Thanks for the reply! Great support, great software.
Have a nice weekend!
