[tor-relays] Tor exit is running but persistently listed as offline by Relay Search

Folks,

I can't figure out why Relay Search is listing the FreeBSD Tor exit node with fingerprint DB00AF98D21464157AF37BE071F858C56F5220F3 as offline. I have last rebooted the node approx. 24 hours ago, and according to the logs Tor is alive (and 'ps' shows Tor is consuming CPU cycles). I have verified IPv4 and IPv6 connectivity and cannot spot any trouble.

Any ideas? The sister exit node (Debian) with near-identical config is chugging along fine.
