Description

Tasks occasionally become stuck in the `TASK_STAGING` state after launching. It appears that this affects both Docker and non-Docker tasks, especially those which start up and fail immediately. Attached is a sample of the slave log as well as screenshots from a testing cluster showing the tasks which are stuck in staging, and then a number of failed tasks which occurs after restarting the slave process. Justin Bieber is provided for scale.

This may be related to MESOS-1837, and quite possibly the same issue, but it remains unclear.
