On further consideration, this looks exactly like Bug 406 on the bug tracker. ( http://bugs.noreply.org/flyspray/index.php?do=details&id=406 ) This is a tricky one; something to do with the way we handle "linked"[*] directory connections on 0.1.2.x servers seems to be broken; I'll try to track it down. (It seems like we're mis-managing the blocked_on_or_conn field somehow; see bug report for more details.) As a workaround, I believe that this bug doesn't appear in the 0.2.0.x-alpha series so far; if you want to try one of those, it may work better for you. On the other hand, it might do worse; it _is_ an alpha after all. :/ [*] (We used to call these internal directory connections "bridged" instead of "linked", but we changed the word when we introduced "bridge servers" in 0.2.0.x, because we wanted to avoid confusing people.) yrs, -- Nick Mathewson
