Resource starvation causes arm to overwhelm server

I'm running a fast relay/exit node and as part of an audit, I ran a DoS attack upon the server which starved system resources.

Once the process was complete, it caused arm to use 51% of system ram, approx 760mb, and 99% of available CPU power.

The chart attached shows CPU during and after the DoS attack, and after 7.04am the light blue shows arm's affect on the server.

A second attachment is (unhelpfully a screenshot) of top showing the resources arm is using.
