Description of problem:
SELinux is preventing 72733A6D61696E20513A526567 from using the 'dac_override' capabilities.

*****  Plugin dac_override (91.4 confidence) suggests   **********************

If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending file and generate the error again.

Turn on full auditing
# auditctl -w /etc/shadow -p w
Try to recreate AVC. Then execute
# ausearch -m avc -ts recent
If you see PATH record check ownership/permissions on file, and fix it,
otherwise report as a bugzilla.

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that 72733A6D61696E20513A526567 should have the dac_override capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c '72733A6D61696E20513A526567' --raw | audit2allow -M my-72733A6D61696E20513A526567
# semodule -X 300 -i my-72733A6D61696E20513A526567.pp

I have the exact same issue, 1195 times 72 hours.

Comment 5 Steve 2018-05-23 11:59:38 UTC
I solved my problem. 
It was rsyslogd. Which was replaced by journal a long time ago.
Removed package and problem solved.
This machine has not had a clean install for many, many years. Always updated and for some reason syslog was never removed during the update process.
