I'm not convinced either of these errors actually stop anything working, they're just annoying.

The first line appears to be an upstream bug in unbound which is making it check root servers with ipv6 even if ipv6 is disabled. It's meant to be fixed eventually. You could manually remove the server from the internal config but you'd have to mount more of the container to get to it.

The second line you can do what it says, and add "net.core.rmem_max = 1048576" to your sysctl on the host.
