Comment (by s7r):

 @dgoulet @asn are we still hunting this? Or should we make this a protocol
 warning?

 The Exit relay where I have received so many of these warnings was taken
 offline for few weeks for the reason of changing office location. I have
 started it again something like little over 24 hours ago and after it got
 measured and left the Unmeasured state it generated about 190 of these
 warnings in less than 8 hours. Same story, just a relay (no client, no
 SocksPort, no onion service hosted).

 It is running something recent of course: 0.3.5.0-alpha-dev (git-
 946428d27382fdd0+c46a0a06f).


 I was able to catch one debug log that contains at least one line of the
 warning, but i am not sure they will be different than the ones I have
 sent you last time. I have checked:

 email me directly for the complete file if you need it.

 I don't see what could be so special about this relay and why is it
 logging this so so much. It's not even an ultra fast one with huge
 consensus weight.
