title: Capture node.js crash reason
body: <p>I have a script written in node.js, it uses 'net' library and communicates with distant service over tcp. This script is started using 'node script.js >> log.txt' command and everything in that script that is logged using console.log() function gets written to log.txt but sometimes script dies and I cannot find a reason and nothing gets logged in log.txt around the time script crashed.</p>
  
  <p>How can I capture crash reason? </p>
