Comment (by galbaras):

 > To clarify, the cron log I attached above shows I have a cron run firing
 every 2 minutes

 Oh, right.

 > The original patch [https://github.com/WordPress/wordpress-
 develop/pull/3726 suggested patch] (just ignore the warning) would fix the
 issue that I am observing on my sites.

 Maybe not, because it prevents duplicates and fixes the error message, but
 if you're not getting duplicates, then it won't stop the problem of
 unschedule/reschedule failures.

 Maybe we should look at environmental issues. How is everyone triggering
 their crons?

 I use the cPanel cron once every 15 minutes and have `DISABLE_WP_CRON`
 defined to block it running on page loads. It's highly unlikely my crons
 run more than once in that timeframe, unless there's a cPanel issue,
 perhaps.

 More specifically, I use a script on a central host to cURL wp-cron.php on
 my sites remotely, in case this matters. And I'm on a shared Litespeed
 server.
