Description Niki Guldbrand 2013-10-30 17:30:20 UTC
Description of problem:
SELinux is preventing /usr/bin/journalctl from using the 'ipc_lock' capabilities.

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

If you believe that journalctl should have the ipc_lock capability 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
