title: PHP CLI Timeout Issue
body: <p>I have a PHP CLI script that continually times out, and I can't figure out the source of the timeout. Seemingly "randomly" the script will stop (with no PHP error in the logs) and give the following output to console:</p>
  
  <pre><code>timeout, elapsed_time = 60
  </code></pre>
  
  <p>I'm setting PHP's time limit via <code>set_time_limit(0);</code> intermittently but it doesn't seem to be making a difference. </p>
  
  <p>Besides that, PHP is supposed to throw an error if it hits its timeout, and no error is thrown, so could this timeout be triggered by something other than PHP? </p>
  
  <p>The script is started by a bash script ".sh" on a Ubuntu machine.</p>
  
  <p>Thanks!</p>
