Thank you for the quick fix/workaround.
I think it is worth opening a ticket, as it indeed does not make
sense, let's say I want to use the port dns/unbound, on a very busy
server, and want to bump the so-sndbuf to 8m. It'll be very
interesting to set net.inet.udp.maxdgram=8388608 in order to appease
the warnings.
