Ian Downes commented on MESOS-856:
----------------------------------

We've observed freeze-thaw loops continuing indefinitely when the processes 
contained in the cgroup were in non-interruptible D state but also for 
processes that are supposedly in runnable R state but cannot be killed with 
kill -9. In this scenario the freezer may actually be freezing but we still 
cannot kill the process(es) and will loop.

We should consider how to handle/report this scenario.

> TasksKiller may run forever because the cgroup cannot be frozen.
