> I have added *taskmanager.jvm-exit-on-oom* flag to the task manager starting
> arguments. During my testing (simulating oom) I noticed that sometimes YARN
> containers were still in RUNNING state even though they should haven been
> killed on OutOfMemory errors with the flag on.
> I could find RUNNING containers with the last log lines like this.
> {code:java}

> When using -XX:+ExitOnOutOfMemoryError JVM flag containers get always
> terminated!
