Subject: Re: [IPv6] "sendmsg: invalid argument" to multicast group after some	time

Well, it'd certainly be good to identify exactly where in
the sendmsg path you're getting the EINVAL from. If
possible, I'd suggest putting in some debugging code
and reproducing it.

 If you can pick up the exact arguments when it's happening
via strace and send those here, that may help, but I wouldn't
expect those to be incorrect from ping6 only some of the
time...

I'll look into this some more if someone doesn't beat me to
it, but I'm travelling now so it will be a few days at least before
I get to it.
