title: Stepping Thread Group does not ramp down
body: <p>I am using STG with OS Process sampler executing a shell script which does some operations in a loop.
  The Ramp up and steady stage works well.</p>
  
  <p>However the Ramp Down does not happen as expected. The threads/shell scripts keep on executing even after the time period has expired.</p>
  
  <p>The setup is in distributed mode.
  and JMeter Logs are showing: "Sampler is not Interruptible"</p>
  
  <p>Please suggest</p>
  
  <p>Regards</p>
