> When running a task with docker and if {{docker inspect}} output size is more than 64k, it fails. The command {{docker inspect}} is blocked. The task remain in ASSIGNED state and after 15mins, the task is KILLED. The subprocess library [1] used in mesos to run this command is not handling the output beyond this size.

> docker pull livecipher/mesos-docker-inspect-64k:1.0 > /dev/null && docker inspect livecipher/mesos-docker-inspect-64k:1.0 > inspect.out && du -sh inspect.out && rm -f inspect.out
>  76K	inspect.out
