> Perhaps because the old broker had 1 CPU core and the new one has 2 CPU
cores? I can imagine that might affect goroutine scheduling which might
affect the visibility of race conditions.
Ah that would do it :) The reason we didn't notice then was because
clients and proxies weren't around to trigger the race until we switched
over the DNS records for the bamsoftware.com domains.

Okay I did this and restarted the broker as of `2019/11/22 22:50:27` that
should work until we get this patch reviewed. Thanks!
