Things to check on:

• Stuff will run as root so make sure that when you sudo su that /usr/local/bin is in your path. You may need to add to the /root/.bashrc file export PATH=/usr/local/bin:$PATH
• When you sudo su check to see if node --version returns v0.8.16.
• ulimit -n should return a value higher than 1024.
