Some of the people were talking about this on Gitter.im. In order to prevent the entire JVM from crashing you may need to only allow "-Xmx50M" as the runtime arguments while deploying GRIP. GRIP does also prefer to have ~90MB of RAM if it's available. Otherwise, you can always work with what you have (adjusting the RAM by 1MB until it stops crashing). "-Xmx50M" -> "-Xmx55M" -> ... -> "-Xmx128M"

There is a confirmed system with a raspberry pi 2, but sometimes the system claims to be running at ~200% CPU usage. It's better off to ignore what the Pi thinks and simply test the functionality when it comes to the raspberry pi 2.

Good luck! Feel free to stop by the gitter.im chat if you have any more questions about GRIP.
