Description of problem:
SELinux is preventing certwatch from 'write' accesses on the directory /dev/mqueue.

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

If you believe that certwatch should be allowed write access on the mqueue directory 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:
# ausearch -c 'certwatch' --raw | audit2allow -M my-certwatch
# semodule -X 300 -i my-certwatch.pp
