asw2-a5-eqiad xe-0/0/36 has some input errors. It's part of ae0, which is the 4-port aggregate back to asw-a-eqiad, and is the only one of the 4 showing the errors. None of the 4 links (or the ae) is showing errors on the other side at asw-a-eqiad. The errors have been there since at least Sep 2013 in librenms's history.
This is possibly related to the pattern of inter-row elevated nutcracker timeout rates shown in: https://phabricator.wikimedia.org/T102199#1499358
I've disabled the link (1/4 from aggregate) on both sides:

bblack@asw-a-eqiad# commitlibrenms graphs show ae0 errors have dropped back to zero.
Leaving this ticket open still to resolve the actual link issue and turn it back on.
I replaced the fiber. Let's turn it up and see if it's any better. Next step would be to replace optics
I turned it up, but it seems there is no link on it now:
