[jira] [Commented] (MESOS-6414) Task cleanup fails when the containers includes cgroups not owned by Mesos

Jie Yu commented on MESOS-6414:
-------------------------------

I cannot fully understand the problem. What do you mean by " a mesos task is launched in a cgroup outside of the context of Mesos"?

> 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.
