title: Nodejs/async not working properly with crontab
body: <p>I have a script that needs to be executed every hour. The script has to download multiple large files from the internet.</p>
  
  <p>The logic is simple.</p>
  
  <ol>
  <li>An array of files to be downloaded.</li>
  <li>Start download each in Serie (async.eachSerie)</li>
  <li>After the download has finished go to next file in the array.</li>
  </ol>
  
  <p>The problem is: I get the message "Your download has started" but I never get back the message 'Your download has finished'.</p>
  
  <p>When I execute the script from command line works perfect. But it is not working with crontab (* * * * * node /path/script.js). The download never finishes.</p>
  
  <p>Am I missing something?</p>
  
  <p>Thank you</p>
