title: What causes an R script to get Killed?
body: <p>I've been running some memory intensive processes on EC2 servers. The code runs quite well for about 12-14 hours (it's running 1000s of simulations on 12-14 large datasets) and then all of a sudden I just see the message "Killed" with no further explanation.</p>
  
  <p>What makes R do that?</p>
