In the future, it would be helpful if you replied to the PR saying so. It looks like it was closed at your request as you stated the problem had gone away, so I've been working under the assumption that the problem has gone away, as that's the last information I have. > I am still 99% sure this is NOT A TOR ISSUE!!!

I have appealed a number of times on the freebsd-security mailing list and eslewhere for information from people who could reproduce the problem. In general the replies I got were that people either had the problem go away with recent 6.x, or that they did not have time or were not interested in helping debug the problem. If you are interested, please take a look at my recent reply to the reported problem, and work through the steps there. I strongly recommend using a serial console on the box. I can only debug a problem if I know it exists, and with enough information, and so far, there's been insufficient information to track down the problem.
