Hi Trond, Steven,

eversince I switched from Debian Jessie to Stretch last summer, I've
been seeing the very same hidden ports on an NFS server as described in
[1], which is a follow-up to [2].

Your patch ([3], [4]) solved the issue back then. Later on, you changed
that fix again in [5], which lead to the situation we're seeing today.

Reverting 0b0ab51 fixes the issue for me.

Let me know if you need more info.


Thanks
Daniel
