this feels odd, as `apache2 reload` should be calling `apachectl
graceful`. Reading the man page:
> graceful Gracefully restarts the Apache daemon by sending it a

The key to me being:
> This differs from a normal restart in that currently open connections
are not aborted.
so it seems like there's a link in openstack services to apache2 running
_continuously_ or else those services lost a handle? I'm guessing
there's a dependency chain in the systemd units for specific openstack
services?
A bit more digging, it looks like apache _requires_ the graceful reload
to pick up the rotated logfile properly.
Could you provide more info on the following:
* what openstack services are running into issues
* journal outputs from the logrotate journal entry. they should be tagged as
`apache2.logrotate` in the journal.
* journal output from openstack services that are having issues at the same
time as the apache2 reload
* any helpful openstack unit files or information that can show the relation
between the services and apache2
right now i can't tell if there's something more that can be done in
apache2 that package vs. an apache2 deployment within the specific
context (default behaviour vs. specific system expectations)
