## Symptoms

- * The QoS Software Blade does not start and displays the error:

  `
  'QoS' is not responding. Verify that 'QoS' is installed on the gateway.

  <br />

* SmartConsole logs show:

  `QoS service was stopped.`

  <br />

* This error appears while you install the QoS policy:

  `Error - Make sure the QoS service is started" while installing QoS policy.`
* When you manually restart the Blade with the `etmstart` command, this error appears:

  `
  [ERROR] etm_register: Failed to send ETMDRV_HOOK ioctl to all devices`  
  `
  [ERROR] etm_register: Failed to send ETMDRV_TIMERS_STATE 1 ioctl to all devices`  
  `
  [ERROR] etmreg: Operation failed: No such file or directory`  
  `
  QoS: 'fgate ctl etmreg on' Failed"`  
  `
  `
* Rebooting the Security Gateway resolves the issue temporarily.
