- [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?
Then when I managed to kill it from the CLI, /resume immediately repeated the behaviour.
What Should Happen?
It should use an appropriate amount of ram and self regulate as soon as it realises its about to bring down the host.
