Vinod Kone commented on MESOS-1765:
-----------------------------------
What is the minimum kernel version required for pid namespaces? If it's not an
old enough kernel, we need to figure out a way to use either freezer (w/ kill)
or pid namespace depending on the kernel version.
> Use PID namespace to avoid freezing cgroup

> There is some known kernel issue when we freeze the whole cgroup upon OOM.
> Mesos probably can just use PID namespace so that we will only need to kill
> the "init" of the pid namespace, instead of freezing all the processes and
> killing them one by one. But I am not quite sure if this would break the
> existing code.
