So it would run 1-4. but it reports EADDRINUSE after bind.
Why?
The stack assumes that SO_REUSEADDR is never cleared on a socket after
it gets set.
How to resolve it? Should I dup() the fd?
Did you close the affected socket in (5) ?
Presumably you are still trying to use the same port; is it a
non-ephemeral port? You might want to consider SO_REUSEPORT although I
believe FreeBSD doesn't fully support it for non-multicast.
