> I have a docker image which starts fine on all my slaves except for one. On
> that one, it is stuck in STAGING for a long time and never starts. The INFO
> log is full of messages like this:

> kwe-vinland-work is the task that is stuck in staging. It is launched by
> marathon. I have launched 161 instances successfully on my cluster. But it
> refuses to launch on this specific slave.
> These machines are all managed via ansible so their configurations are /
> should be identical. I have re-run my ansible scripts and rebooted the
> machines to no avail.
> It's been in this state for almost 30 minutes. You can see the mesos docker
> executor is still running:
