Hey @steersbob, I see you linked to moby/moby#38203. I'm facing this exact same issue. Is ipv6 the solution to avoid service restarts on the node?
Nvm, found a potential solution here, might help you as well. moby/moby#36311
@jpaarhuis Probably. We can reproduce the problem, and the problem goes away when IPv6 is enabled per https://docs.docker.com/config/daemon/ipv6/. This doesn't mean I can confidently say I understand the issue and its solution.
Edit: to be explicit, we are running a docker-compose environment - not swarm.
Ok, we do run swarm and it seems like a specific issue to swarm. We're trying out this solution now: moby/moby#36311.
Editing the docker daemon config seems to consistently fix the issue on all supported platforms. Closing this issue now.
