Definitely not tunerless (1 x HDHomerun + 1 x dual PCI).

So, does this indicate backend is running twice?

If so, what is likely to cause that?

What else should I look for in the logs?

I know another issue is that on boot, with the frontend in the startup
applications, the frontend says that it can't connect to the backend for
a short while (30 sec or so?).

Could that be related? If so, I guess that has to be investigated first.

Network is wired.
