Please paste your entire torrc (without any sensitive data of course). We have some slight misbehavior for the IPv6 auto discovery.

Along with the torrc please state if you have IPv6 of any kind to that box and if yes which kind (tunnel, native, etc.).
No IPv6 anywhere around.
Also, you might use `ORPort 9001 IPv4Only` in torrc without any other modifications besides this and see if the error still occurs.
This did the trick! No messages in the last 5 hours, since when I updated torrc and restarted Tor.
Thanks! Marco
