UDP ports can be open by multiple processes if in broadcast mode .. but this requires binding to an interface that supports UDP broadcasting. I don’t have a Mac to test this on, but it apparently can require a bit of config .. see: [Multicast overlays · gossiperl/gossiperl Wiki · GitHub](https://github.com/gossiperl/gossiperl/wiki/multicast-overlays#setting-up-multicast-on-os-x)

Would be interested to know if that resolves it for you …
