You are right. the plug(s) should not be there. Thank you for the hint. However, I do not understand why all the plugs stays alive. My current approach is to kill them at strategical points.

Edit: The "plug(s)" are waiting until they can write to fifo, same with "sd". I think I should modify those to scripts, so that they only try to write if nickel is running.
