Comment 6 for bug 1825584

As a follow up of the the thread on the ML [1], it appears that the AMQP hearbeat issues that we were seeing in other OpenStack services running under Apache mod_wsgi were due to a change in container healthcheck.

In Stein, TripleO configures the interval between two healthchecks to be 60s + random(45)s, which is too long to ensure that mod_wsgi can always schedule eventlet timers and answers to AMQP heartbeat packets in a timely manner.

The work to fix that specific problem is tracked in https://bugs.launchpad.net/tripleo/+bug/1826281
