title: what can cause node.js to print Killed and exit?
body: <p>I have a Node.js app that loads some data from Mysql into Redis when the app starts. It has been working fine up until we modified the data in Mysql.</p>
  <p>Now it is just exiting with a <code>Killed</code> message.</p>
  <p>I am trying to pinpoint the problem but is is hard to debug using the node-inspector as the problem doesn't appear when running in --debug.</p>
  <p>I don't think my problem is in the data itself because it works on my local machine but doesn't work on my production box.</p>
  <p>My question is, what causes the <code>Killed</code> message? Is it Node.js or is it in the Mysql driver or elsewhere?</p>
