Please see:
https://bugzilla.redhat.com/show_bug.cgi?id=805397

If you don't put "ControlGroup=cpu:/" in the "[Service]" section, the realtime scheduling setting will get a permission denied and the watchdog will eventually miss it's deadline.

I have just had my machine reboot twice due to this....
