I've seen this when I've renumbered vsites on the server and the old IP was
no longer resolvable via DNS. Either there's an issue with your DNS
server caching old IP info for certain domains, or else you've still got
"remnants" of old IP addresses on your server someplace (maybe in
/etc/hosts or something?) that it's trying to resolve.
