Additional info:

We think this is coming from health checks as it's written out to logs periodically. There are two containers unhealthy:

[root@controller-0 ~]# docker ps | grep unhealthy
3f3506aad44a        192.168.24.1:8787/rhosp13/openstack-gnocchi-statsd:2018-09-28.1              "kolla_start"            12 days ago         Up 12 days (unhealthy)                       gnocchi_statsd
