We are running Docker Swarm on Debian bare metal for 3 years, never had such an issue.

Is your distro up to date?

What’s the infra around it, do they reset the network every month or quietly move VMs to different hosts for maintenance?

You could file a bug on swarmkit Github, but response for Swarm is usually slow to non-existent.
