"Closing no-longer-configured OR listener" does not put brackets around IPv6 addresses
When I was setting IPv4Only on a new Tor relay with broken IPv6, and did killall -HUP tor, I got this:
Dec 23 20:08:02.000 [notice] Closing no-longer-configured OR listener on :::143(I believe) the :::143 should be [::]:143.
