title: JMeter doesnt stop its execution even after the scheduled duration
body: <p>Below is the details of my test plan.  </p>
  
  <blockquote>
    <p>Number of Threads : 700<br>
    Loop Count : Forever   Scheduler<br>
    Configuration : Duration : 250 seconds</p>
  </blockquote>
  
  <p>At 250th second, threads begin to stop as the scheduled duration is reached.
  Even after 30 mins, the last 23 threads are not stopped and the test is not completed.</p>
  
  <p>Tried to run the same test through non GUI mode as well. But the response is same.
  Even after 30 mins, the test doesn't stop its execution.</p>
  
  <p>Can you please help if i have missed any configuration..</p>
