             Summary: Task cleanup fails when the containers includes cgroups 
not owned by Mesos
                 Key: MESOS-6414
             Project: Mesos
          Issue Type: Bug
          Components: cgroups
            Reporter: Anindya Sinha
            Assignee: Anindya Sinha
            Priority: Minor

If a mesos task is launched in a cgroup outside of the context of Mesos,  Mesos 
is unaware of that cgroup created in the task context.

Now when the Mesos task terminates: Mesos tries to cleanup all cgroups within 
the top level cgroup it knows about. If the cgroup created in the task context 
exists when LinuxLauncherProcess::destroy() is called but is eventually cleaned 
up by the container before we do a freeze() or thaw() or remove(), it fails at 
those stages leading to an incomplete cleanup of the container.
