--- Comment #33 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
> It still leaks. The memory leak is unimportant problem.

No, I don't think so. Every multicast rule generates a multicast address for
the network interface. When a rule is dangeling, I suspect the multicast
programming of the network interface may become incorrect, so the multicast
traffic gets dropped.

Can you try playing with promiscious mode when there is no ping6 response?
