Capelinhos

This gem gracefully stops Passenger Ruby processes that have exceeded a memory threshold. It is meant to be added to cron and run at an interval of your choosing.

If Phusion Passenger is configured with PassengerMinInstances and the number of processes is under that number, then a new process should replace the processes that were shutdown.

TODO

• Implement support for multiple Passenger Instances
