title: Calling password_hash multiple times throws 503
body: <p>I have a large number of users and I want to change theirs passwords to a more secure hash.</p>
  
  <p>However, if <code>$users</code> is an array with more than 1250 elements, my Vagrant throws a 503. I tried to increase the number of cores for the VM, but the result is the same.</p>
  
  <pre><code>foreach ($users as $user) {
      $password = password_hash($user['password'], PASSWORD_DEFAULT);    
  }
  </code></pre>
