24864	Django will not listen to same port on IPv4 and IPv6 at the same time	Erik Nordstroem	nobody	"By itself, `python3 manage.py runserver 0.0.0.0:8000` works.

By itself, `python3 manage.py runserver [::]:8000` works.

But if I try first `python3 manage.py runserver 0.0.0.0:8000` and then `python3 manage.py runserver[::]:8000`, I am told, incorrectly, by the second process that:

    Error: That port is already in use.

Same goes if I run `python3 manage.py runserver [::]:8000` first followed by `python3 manage.py runserver 0.0.0.0:8000`; the first process runs but the second process will report:

    Error: That port is already in use."	New feature	closed	Core (Other)	1.8	Normal	wontfix			Unreviewed	0	0	0	0	0	0
