In additional, may you share the details about how to reproduce this? I would 
like to verify if cgroups namespace could resolve this or not [~anindya.sinha]

> Task cleanup fails when the containers includes cgroups not owned by Mesos

>                 Key: MESOS-6414
>                 URL: https://issues.apache.org/jira/browse/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.
