Description Barry Smith 2013-07-21 19:58:56 EDT
Description of problem:
It seems to happen when logwatch runs.
SELinux is preventing /usr/sbin/mdadm from 'read' accesses on the chr_file fw0.

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

If you believe that mdadm should be allowed read access on the fw0 chr_file 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:
# grep mdadm /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
