Interesting. This affects only one of three exit relay processes, which
are all on one machine and use exactly the same config (and a local
unbound):

# diff /etc/tor/instances/0/torrc /etc/tor/instances/2/torrc
1,4c1,4
< Nickname sofia # sponsored name!
< ORPort 77.247.181.162:443
< DirPort 77.247.181.162:80

# cat /etc/resolv.conf
nameserver 127.0.0.1
nameserver ::1

I used the opportunity to reboot the machine to install the latest
kernel and upgrade Tor. Let's check again in a day or so if the problem
persists.
