title: NodeJS: MySQL sometimes raises ETIMEDOUT error
body: <p>I'm currently developing an application using NodeJS.</p>
  
  <p>However, often the server throws this error, and I can't interact with mysql.</p>
  
  <pre><code> [Error: read ETIMEDOUT]
    code: 'ETIMEDOUT',
    errno: 'ETIMEDOUT',
    syscall: 'read',
    fatal: true }
  { [Error: Cannot enqueue Query after fatal error.] code: 'PROTOCOL_ENQUEUE_AFTER_FATAL_ERROR', fatal: false }
  </code></pre>
  
  <p>Does someone have a solution to fix that? </p>
  
  <p>Thanks </p>
