} Are your netgraph modules up-to-date and kernel in sync?
Yup. Did a full upgrade yesterday afternoon, including mpd 3.10.

That looks like it works. Can't figure out how to delete the
new node, though. Oh, nevermind, it went away with the ngctl
session.
} If that works, then try enabling netgraph debugging in mpd
} and ngctl and compare the messages going back & forth.
Well, they're different, but I'm not good enough friends with
netgraph to figure out what's making it unhappy.

My *** aha! is that the sin_len in the sockaddr_in being sent with the
