f26->f27 server upgrade, starting system activity accounting tool every 10 minutes

Fedora 26 Server was upgraded to Fedora 27 with 'dnf system-upgrade'
so it is no longer strictly the Server product I guess:
$ cat /etc/fedora-release
Fedora release 27 (Twenty Seven)

I'm seeing in the journal, a lot more activity than I'm used to.
Usually it's just once an hour, dnf makecache timer triggers. But I
noticed many reached and stopped target Basic System:

Nov 12 06:25:02 f27s.localdomain systemd[5593]: Reached target Basic System.
Nov 12 06:25:52 f27s.localdomain systemd[5593]: Stopped target Basic System.
Nov 12 06:28:01 f27s.localdomain systemd[5647]: Reached target Basic System.
Nov 12 06:28:51 f27s.localdomain systemd[5647]: Stopped target Basic System.
Nov 12 06:55:02 f27s.localdomain systemd[5716]: Reached target Basic System.
Nov 12 06:55:52 f27s.localdomain systemd[5716]: Stopped target Basic System.

Nov 12 07:25:01 f27s.localdomain systemd[5870]: Reached target Basic System.
Nov 12 07:25:51 f27s.localdomain systemd[5870]: Stopped target Basic System.
Nov 12 07:28:02 f27s.localdomain systemd[5916]: Reached target Basic System.
Nov 12 07:28:52 f27s.localdomain systemd[5916]: Stopped target Basic System.
Nov 12 07:55:01 f27s.localdomain systemd[5992]: Reached target Basic System.
Nov 12 07:55:51 f27s.localdomain systemd[5992]: Stopped target Basic System.

But I can't really figure out why. And so then I noticed the system
activity accounting tool only starts, but keeps starting every 10
minutes.

Nov 12 10:00:11 f27s.localdomain systemd[1]: Starting system activity
accounting tool...
Nov 12 10:00:11 f27s.localdomain systemd[1]: Started system activity
accounting tool.
Nov 12 10:10:06 f27s.localdomain systemd[1]: Starting system activity
accounting tool...
Nov 12 10:10:06 f27s.localdomain systemd[1]: Started system activity
accounting tool.
Nov 12 10:20:06 f27s.localdomain systemd[1]: Starting system activity
accounting tool...
Nov 12 10:20:06 f27s.localdomain systemd[1]: Started system activity
accounting tool.

There's also many instances of creating and removing slice User Slice
of pcp. But I don't understand it well enough yet to figure out if
these are related or separate.

I relabeled the system after the upgrade, and 'ausearch -m AVC' turns
up nothing, but the journal does have many USER_AVC messages in it.

Nov 12 08:28:26 f27s.localdomain audit[727]: USER_AVC pid=727 uid=81
auid=4294967295 ses=4294967295

Anyway, I'm going to post the complete journal while I'm still digging
into it. There may be more than one thing going on here...
