Comment (by s7r):

 My relay running 0.3.1.2-alpha-dev (git-1763aa058b08a1c5)reported this on
 Jul 01 (yesterday) and Jul 02 (today) more than usual (it usually logs
 this warn few times per month) but just yesterday and today 24 times, at
 few hours interval between each warning.

 Maybe this occurs when the relay in question is being used as an
 introduction point (or HSDir maybe) that someone tries to attack / de-
 anonymize using some weird technique? I am keeping an eye on this and I
 can't find a logical explanation why sometimes we see it, sometimes not...
 not being able to reproduce sucks.
