the patch on the other bug is only for the overcloud, this bug is for the undercloud
This bug did not make the OSP 8.0 release. It is being deferred to OSP 10.
Currently working on this upstream to reduce the overall number of workers for the services, https://review.openstack.org/#/c/386696/
This seems to work better and better on each major version. With current major version (11) I managed to keep an undercloud and controllers with less than the documented minimum on a virtual setup and it only started to hiccup after 2 weeks which I am fine with.
Since the problem described in this bug report should be
