Has anyone seen this behaviour before?

I have 2 Linux primary servers in a zone, freshly upgraded to 11.2.1.

But 12 times a day, I get this warning:
Full Message: Unable to perform the action. The bundles of type Linux
Bundle are disabled.
Additional Information: None
Severity: Warning
Message ID: BUNDLE.TypeDisabled
Probable Cause URL: None
Related Objects: None

I have tried and search all bundles for type "--Linux Bundle".
But nothing comes up.

Both servers reports this error exactly 12 times a day.
