title: docker-compose down failing: Too many open files
body: <p>I'm using docker-compose in my production server. On my deploy process I run <code>docker-compose down</code>, deploy the application and run <code>docker-compose up</code>. However when I do <code>docker-compose down</code> it returns something like that:</p>
  
  <pre><code>ERROR: for ubuntu_php_run_1105  ('Connection aborted.', error(24, 'Too many open files'))
  
  ERROR: for ubuntu_php_run_821  ('Connection aborted.', error(24, 'Too many open files'))
  
  ERROR: for ubuntu_php_run_820  ('Connection aborted.', error(24, 'Too many open files'))
  </code></pre>
  
  <p>If I run this command manually more times eventually it succeeds but I need to fix it because this error makes my deploy process to fail.</p>
