Ok, I've just had issues this morning, and went and *looked*. I can see a yum-cron running monthly, sure. Running weekly, I guess. Running daily? Why?
And there is *NO* reason whatever for a "yum-hourly*. None. This is CentOS, not ubuntu-snapshot-of-the-moment.
I don't know if this is from upstream or not, but it's wrong. I mean, even Redmond only pushes out patches once or twice a month, except for critical fixes.,,,.
