Octane rendering nothing?

I don't understand what's happened...
I was rendering 4096*4096 just fine and every once in a while it doesn't render anything. I'm not sure why this happens. It loads the data to the cards, but there is no activity.
Any thoughts?

I found that it has to do with the alpha channel toggle in the mesh preview kernel. Can someone explain this?

Is it possible, that you run out of memory? The film buffer with an additional alpha channel requires more memory. Does that also happen at lower resolutions?

I see. I was taking into account the film buffer, but didn't put any thought into the additional alpha channel. I wasn't even intending on rendering with alpha, it was enabled for some reason.
Thanks for your insight!
