The issue here happens because of two bugs.

First is https://bugs.torproject.org/24767 where the flood of circuits
causes us to make a flood of connection attempts to relays that are down.

And second is https://bugs.torproject.org/projects/25061 (which I just
filed) where each of these connection failures gets sent to the "warn
about bootstrapping failure" code.

So I think these warnings are not actually related to your relay's guard
(and that's the bug).

I think this statement is still true. The warnings are harmless.
