The most helpful thing from my point of view would be to try to figure out whether there's any pattern to the failures. Are some versions of Tor broken for DNS lookups? If so, that's the problem we should try to fix first. If you can identify any servers that fail on lookups particularly often, that would be a great place to start.

I'm happy to report that after a couple of weeks of scanning, I found no Tor servers that returned incorrect DNS information. However, whenever I get a DNS lookup failure, SOAT reports the last exit node as 0. Mike, does this mean it was unable to establish a circuit?
