FWIW, the Pi-hole project embeds dnsmasq without any special docker alterations and is known to work fine in docker without restarting for months or even years non-stop without such issues.
Also worth considering are issues with docker-proxy - maybe the interface goes down temporarily and the configuration is to bind to the interface instead of to the wildcard address, or ... Many possibilities and the more we know, the better. I really doubt there is anything systematic concerning dnsmasq in docker but rather something related to the particular container or the particular configuration. Best, Dominik >Am 25.
