Stop setting both.
Set only SO_REUSEPORT. SO_REUSEPORT is for UDP. SO_REUSEADDR is for
TCP listening sockets. SO_REUSEADDR makes it possible to kill a
server process and start it again without having to wait for a
timeout on the old TCP sockets.

By setting the socket options SO_REUSEADDR and
SO_REUSEPORT, I've been able to successfully get two
instances of the same process running as the same user
to bind and share the same UDP port on OS X. However,
if the two instances of the process are running as
different user ids, the bind attempt by the second
instance of the process fails with "address already in
use". Does anyone know if there is way to get two
instances of the same process running as different
user ids to reuse the same UDP port on Mac OS X?
Thanks,
Michelle
