title: jmeter hangs up and won't return
body: <p>I am running 340 concurrent users to load test on server using jmeter. </p>
  
  <p>But on most of the cases jmeter hangs up and won' t return, even if I try to close the connection it just hangs up. and eventually I have to close the application. </p>
  
  <p>Any idea how to check what is holding the requests and how to check the requests sent by jmeter and find the bottleneck.</p>
  
  <p>Got the following message on closing the thread</p>
