Strange network error: "Martian source"

[zackman0010]

We use Rootless Podman as part of our CI/CD process to build Java services. Our CI/CD server uses docker-compose, which uses the Podman-Docker compatibility layer to run the containers. However, on some random builds, the job locks up with no activity. Looking in the journal, I see a lot of messages about "IPv4 martian source", which makes me believe there's something weird going on with the network connectivity. It's completely random when it happens, I haven't been able to find any differences between the ones that work and the ones that get locked up. Does anyone have any suggestions on what might be causing this?

Podman version: 4.6.1 (Latest available from RHEL 8 repositories)
OS: RHEL 8.9
