Received data would make the buffer exceed the maximum limit, buffer dropped
I've gotten around this by having a script restart the docker container every hour, but was wondering if you had any ideas about the below?
Standard docker install from your repo with the suggested run arguments. Only difference is im running a CNI so using the broker command..

It sounds like that part of the code got itself wedged.
Can you make a packet capture of the communications on the Raspberry Pi leading up to that point? You should be able to do this with:
sudo tcpdump -i eth0 -p -w capture.pcap 'host 192.0.2.1'
Replace eth0 with the appropriate network device, and 192.0.2.1 with your CNI's IP address.
@micolous I see you had a branch to change these exceptions to warnings; any chance this could get merged? https://github.com/micolous/cbus/compare/master...buffer-size
