title: Does the 'max_user_connections' resource error resolve if I change the server on Heroku
body: <p>I have deployed my Rails (3.2.13) app on heroku (its almost 3 years for deployment). That time I have used unicorn as a server.</p>
  
  <p>I have used ClearDB addon for setting mysql database on Heroku.</p>
  
  <p>Currently I am facing issue where I am getting following error</p>
  
  <pre><code>Mysql2::Error (User 'username' has exceeded the 'max_questions' resource (current value: 54000)): 
  </code></pre>
  
  <p>I referred <a href="https://stackoverflow.com/questions/17937390/resque-mysql2error-user-has-exceeded-the-max-user-connections-resource-cur">this answer</a> where he has suggested </p>
  
  <ul>
  <li><p>Scale up your database by upgrading to a higher ClearDB plan (<a href="http://dashboard.heroku.com" rel="nofollow noreferrer">http://dashboard.heroku.com</a>)</p>
  
  <p>But I am already on the highest clearDB plan</p></li>
  <li><p>Scale down your application by reducing the number of dynos/workers (heroku ps:scale command)</p>
  
  <p>for this I have already reduced my worker dynos.</p></li>
  </ul>
  
  <p>But Still facing the issue.</p>
  
  <p>Can any one provide me other solution that would be great.</p>
  
  <p>Should I move from unicorn to puma server? </p>
