   @gianm here is a video of the overlord console:
   https://www.screencast.com/t/z4eXgbaGe5fy
   
   as you can see, the tasks dont really product any output at all. which is what makes it really tough to debug this issue. (ignore the dripstat agent output in the logs in the video, they dont affect the tasks)
   they just start and shut down.
   
   the video shows that the one replica seems to be working, but we had to take down the other replica since it kept on spawing new tasks (which fail) almost every minute.
   
   the coordinator(+overlord) show that it tries to spawn the tasks, but it cannot connect to it, so it seems to kill it. (coordinator logs are in the users-group thread i linked to).
