Comment (by ryandesign):

 Eric, it would be great if you could try my PR and let me know if that
 fixes the problem for you. If not, you could try reducing
 max_hosts_to_ping in my PR from 50 to 30 or something. If would also be
 good to know if you see any other problems as a result of using my PR.
