[MQTT] OH 3.0.0.M1 suddenly stopped working

I was just about to change my operational OH2.5 to OH3 M1 because it was quite stable. Unfortunately MQTT stopped spontaneously yesterday. I could’t find any error / exception in the logs. So not much useful info yet to create an issue.

Symptom: When moving a dimmer slider to a new position, it jumped back to the previous position. Dimmer itself not changed either. (I also use ZWave, which did not show this behaviour)

Restarted bundles: mqtt-transport and mqtt-broker-binding
No effect.

Restart OH: System back to normal.

Note: MQTT log level was set to TRACE, I do not know if this might introduce any side effects.

Anyone experienced a similar problem with OH3 M1 ?

Similar error on openHAB 3.0.1 Release Build

System: OH 3.0.1 → MySensensors MQTT Bridge → Mosquitto → MySensors MQTT Gateway

Fresh OpenHab install on debian, system start without any error, running about 1 day, then cannot communicate via MQTT. Messages does not arrive from Mosquitto to OH, also no outgoing messages to the broker. Checked mosquitto with MQTT Explorer, thats seems working, there are messages from the MySensorsGW.
There aren’t any clue in logs ( working untill ~2021-04-13 10:27:12:757) :
