Sure thing, here is the AVC in the /var/log/messages file. I don't see this in /var/log/audit/audit.log but I see other logs in there.
Sep 20 09:03:14 redacted kernel: type=1400 audit(1505916193.999:16716): avc: denied { read } for pid=33245 comm="in:imfile" name="named.log" dev="dm-9" ino=143 scontext=system_u:system_r:syslogd_t:s0 tcontext=system_u:object_r:named_cache_t:s0 tclass=file
Srangely, auditd doesn't seem to be running and systemctl can't interact with it. Possibly because of a dependency
Failed to stop auditd.service: Operation refused, unit auditd.service may be requested by dependency only.
See system logs and 'systemctl status auditd.service' for details.

Good question, is auditd running and writing other events? Also, it will be very helpful if you attach your AVC. There can be situation when auditd is not running yet during boot, so AVCs are logged into journal/syslog.
Please attach AVC and we can move forward.
