Description Frank Murphy 2013-11-25 06:10:39 UTC
Description of problem:
Not too sure,  started yesterday. Possible after systemd update?.
Local fix per alert has not solved problem.
SELinux is preventing /usr/bin/journalctl from 'read' accesses on the file system.journal.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that journalctl should be allowed read access on the system.journal file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep journalctl /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
