Mosquitto - and it has been in place for approx 3+ years without this issue.
In PaperUI I see MQTT binding (2.5.3) installed; under services I can see a service called “MQTT system broker connection”. Could this cause a problem?
I changed the loglevel first to trace, then to debug - when I did this, the messages stopped for approx. 10 seconds. Afterwards it went back the “flooding” mode. Need to download the logfile(s) as I’m unable to see anything with frontail
It’s an RPi, but only the boot partition is on SD card, the rest has been moved to an USB SSD two years ago. After a few hours the problem vanished and I don’t know why. But at least it’s working again.
