title: Jmeter throws "socketexception: connection reset" error during execution
body: <p>The target for us to achieve is 500 concurrent users.
  We have tried running a test for 100 users over 3 machines. And it ran fine without any errors.
  When i tried running the test for 150 or More users with same number of machines, i started getting the following response code</p>
  <p>Response code:Non Http Response code:java.net.socketException
  Response message:Connection Reset</p>
  <p>I have also tried increasing the number of machines to 8 machines. Still it is of no help. Response time is also very high (156 seconds) for some of the requests.</p>
  <p>When we checked the server logs to find out what could be causing this issue, <strong>No error logs were found</strong> there during the time of the execution.</p>
  <p>I'm having a hard time finding out what could be the issue. The server side is ruling out if there could be an issue from their end.</p>
  <p>Tried the following fixes from Jmeter side:</p>
  <ol>
  <li>Increasing the heap size</li>
  <li>Changing the retry count in user.properties file</li>
  <li>Changing Boolean=True in hc.parameters file</li>
  <li>Used HTTP Request Defaulters to change the implementation to HTTPClient4</li>
  </ol>
