Comment 2 for bug 1161175

Just checked, and these values are actually correctly integers in oslo-incubator, so that project doesn't actually have the issue...

    cfg.IntOpt('matchmaker_heartbeat_freq',
               default=300,
               help='Heartbeat frequency'),
    cfg.IntOpt('matchmaker_heartbeat_ttl',
               default=600,
               help='Heartbeat time-to-live.'),
