Bug Description
Hi,
The u-r-c charm, or something, seems to be causing apache2 to periodically graceful. It should only do so on config changes.
This can lead to cgid failing to start on graceful restart/reload:
| [Thu Feb 18 13:09:19.328252 2021] [core:notice] [pid 3630124:tid 139732453542976] AH00094: Command line: '/usr/sbin/apache2'

| [Thu Feb 18 13:09:20.382773 2021] [cgid:crit] [pid 3630124:tid 139732453542976] AH01238: cgid daemon failed to initialize
The health-check relies on cgid being up so units are taken offline in these cases until the next graceful restart/reload.

Seems to be hourly so likely with the metadata sync.
