server incorrectly believes IP address has changed

Tue Nov 20 15:59:24 UTC 2007

If you did not specify your IP within the torrc, tor tries to guess it 
based on your hostname ... and this goes wrong if the DNS is wrong!
I think messages related to this are at info level, so you can have a 
look at info level logs.

If you are running on Linux, look at your /etc/hosts file.
Check also what you get from DNS lookup for your hostname with 
"nslookup" (both Linux and Windows).
