title: JMeter getting hanging in GUI mode
body: <p>I'm having problem with jmeter while running the test plan. Suddenly my Jmeter starts hanging and appears as a black screen in GUI mode. I was running recording controller with multiple thread groups (4 thread groups). Each thread group with 25 users.</p>
  
  <p>I'm using Jmeter 2.11 (current version). I'm not sure whether it is due to overload or some other reason.</p>
  
  <p>Regards
