Your relay has probably chosen some overloaded guards. The problem comes from the extra load on those machines, not your relay. Your relay will eventually try other guards.

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).
As long as your relay is fine, there is nothing you can do here.
I think this statement is still true. The warnings are harmless.
