Yum Updates Broken?

I received an email with this in it?

What does it mean?

I have been seeing this periodically, too. I did find a bugtracker item for CentOS on this issue dating back to May 2017, but it does not seem to have been fixed.

In my case, it appears regularly, and then doesn’t show up as an issue for a while, before it returns.

Here’s the bug track entry I have found: https://bugs.centos.org/view.php?id=13289. It’s marked as a non-critical error.

Based on the log file, it implies that this runs every hour. I have not received this error again, so it has run many times successfully since.

I received another email detailing updates that were being installed on my machine, so it is working.

How often are updates like this pushed out? I have subscribed to receive stable updates, so I assume this is a stable update package? Or are stable updates and yum updates a separate thing?
