RFXCOM - Python asserts and backtrace during each time the HASS docker container stops or restarts, but works anyway #136368
Description
The problem
Each time I stop or restart home assistant I get the following in the docker logs for the container:
s6-rc: info: service legacy-services: stopping

However the integration appears to still work correctly: I get data from my temp+humidity sensor (which is the only thing left on 433 MHz, I have otherwise switched to zigbee).
I don't know when this started, I only recently set up proper monitoring of docker logs using Grafana Loki. I'm pretty sure this didn't happen a year ago or so though. But that is a huge span.
