the scheduler insert an empty line with succeeded = 1. I did not trace down exactly the problem. But remove these lines or clear your table called Schedule.

But first of all you might still have the module Dotnetnuke.Module.Discussions in you module definitions. Remove this module, since it is not supported anymore. So the dll is missing and the business controller is invalid. I believe the scheduler tries to find the dll, but cannot find it and that the scheduler is not full proof to stop logging in the scheduler history. So an duplicate key (NULL key) arises.

I hope this is part or the complete solution. I will post again if the problem is not solved by only removing this module (PAY ATTENTION TO THE FACT THAT YOUR CONTENT WILL BE REMOVED AS WELL! besides the module will probably not work anymore, you might want to keep such information).
