title: WSO2 ESB > Message Processor > Continuous operation Message Processor
body: <p>When the backend is down, I would like to keep the Message Processor always active without having to drop any pending message and without having the necessity of reactivating the Message Processor manually. </p>
  
  <p>I have three suggestions to solve. I think from better to worse. Can you send an example?</p>
  
  <ol>
  <li><p>Use some kind of Quartz configuration file path to keep the Message Processor active always.</p></li>
  <li><p>Could you give value '-1' to the max.delivery.attempts parameter to get a continuous execution of the message processor?</p></li>
  <li><p>Set parameter max.delivery.attempts with a very large number.</p></li>
  </ol>
  
  <p>Thanks</p>
