A lot of people are reporting that SR is down http://dkn255hz262ypmii.onion/index.php?topic=93352.0 Based on information in this email: http://www.mail-archive.com/tor-bugs@lists.torproject.org/msg00010.html "When a hidden service is restarted the old intro points are not valid anymore. Tor seems to notice this and will fetch a new descriptor when it has run out of intro points but then after doing this expensive operation it simply discards it with the excuse that there is already *some* descriptor there. The expensive operation of fetching has been done for nothing. The next time it will again try the old descriptor of which it already *knows* that there are no valid intro points and fetch a new one (possibly better one) again, but only to discard it without even looking at it, again and again and again." So I think you're getting that message because SR is either down or got restarted and your client can't connect to it at the intro points.
