I recently installed and upgraded an OBIEE 12c instance from an 11g instance and am in the process of cleaning things up.

I noticed in my 12c error logs the following error

[43065] The connection with Cluster Controller ::ffff:130.63.37.43.59372 was lost.

I see it popping up quite a few times in my logs, though everything appears to be normal when accessing OBIEE.

I actually have my 12c instance NOT set up as a cluster controller at all.

Would anyone know where or what I can do to fix this error?

This is more of a cleaning house task, as it does not seem to be affecting anything. But I rather make sure my installation is as clean as possible before letting the masses in.
