[Dnsmasq-discuss] dnsmasq in docker container

[Danil Smirnov]

Hi,

There is some evidence on the Internet that dnsmasq doesn't play well with
Docker (when run in a Docker container), i.e.:

https://www.reddit.com/r/homelab/comments/1d7w3l9/struggling_to_diagnose_irregular_hangs_with/
https://github.com/dockur/dnsmasq/issues/7

I have also faced the same issue - after some hours/days, dnsmasq becomes
irresponsive and can't be fixed by e.g. docker kill --signal=SIGHUP, but
only by the container restart. Memory consumption didn't grow and no
errors/warnings were found in the logs.

Are there any suspects we can consider and start checking how to fix?

BR,
Danil
