How reproducible:
Looking at the previous filed bugzilla: 1367162. It was 100% then. This warning occurs when navigating to any page in the Satellite web UI.

Unfortunately, I do not know how reproducible it is currently.

Additional info:
This spamming of the logs is low severity, but can be misleading to the user and make actual errors less easily noticeable.
