> h4. (1) Agent doesn't detect that a pod task exits/crashes
> # Create a Marathon pod with two containers which just do {{sleep 10000}}.
> # Restart the Mesos agent on the node the pod got launched.
> # Kill one of the pod tasks
> *Expected result*: The Mesos agent detects that one of the tasks got killed, and forwards {{TASK_FAILED}} status to Marathon.
> *Actual result*: The Mesos agent does nothing, and the Mesos master thinks that both tasks are running just fine. Marathon doesn't take any action because it doesn't receive any update from Mesos.
> h4. (2) After the agent restart, it detects that the task crashed, forwards the correct status update, but the other task stays in {{TASK_KILLING}} state forever
> # Perform steps in (1).
> # Restart the Mesos agent
> *Expected result*: The Mesos agent detects that one of the tasks got crashed, forwards the corresponding status update, and kills the other task too.
> *Actual result*: The Mesos agent detects that one of the tasks got crashed, forwards the corresponding status update, but the other task stays in `TASK_KILLING` state forever.
> Please note, that after another agent restart, the other tasks gets finally killed and the correct status updates get propagated all the way to Marathon.
