(was: Processes can be stuck in D state and block container destroy)
> Processes can be stuck in D state and prevent container destroy
> ---------------------------------------------------------------
>
> Key: MESOS-2421
> URL: https://issues.apache.org/jira/browse/MESOS-2421
> Project: Mesos
> Issue Type: Bug
> Components: isolation
> Affects Versions: 0.21.1
> Environment: CentOS, 3.10 kernel
> Reporter: Ian Downes
> Labels: twitter
>
> We've observed processes getting stuck in D state (uninterruptible sleep)
> when using the cpu isolator. This prevents the MesosContainerizer launcher
> from killing all container processes and blocks destroying the container.
> It appears to be a kernel scheduler bug: the processes can be unstuck by
> modifying the cpu.cfs_quota_us for the cpu cgroup. This seems to run the
> processes, deliver the kill signal, and they exit.
> We should implement this workaround in the launcher destroy path when
> processes are observed to be in D state.
