Puppet learning VM stopping services

The Puppet Learning VM from Puppet Labs can get hung processes do to limited resources.  Puppet provides a undocumented script to cycle the processes to run as user root:  /usr/local/bin/stop_classroom_services.rb all -f
There is a script to restart them that I don't have handy, something like start_classroom_services.rb

My experience is that the Learning VM runs well for about a week, then it needs to be rebuilt.  I find it more convenient to just build a Puppet Master.
