[GitHub] [mesos] abudnik commented on pull request #388: Fixed a bug where the cgroup task killer leaves the cgroup frozen.

   IIRC, Mesos leaves a task in the KILLING state if `cgroup::destroy()` fails or hangs. The agent can't force the kernel to deallocate resources in the cgroup, so it leaves the task in that state to prevent resource leaks. Otherwise, the agent would eventually allocate all resources of the host on a buggy kernel.
   
   I remember a few jira tickets describing similar issues. Maybe it would make more sense to add some links as there have been investigations some time ago.
