title: JMeter error when generating dashboard at end of test
body: <p>For the last few weeks I have been using JMeters automatic dashboard generation at end of test w/ command: <br></p>
  
  <pre><code>./jmeter -n -t &lt;test JMX file&gt; -l &lt;test log file&gt; -e -o &lt;Path to output folder&gt;
  </code></pre>
  
  <p>However about 50% of the time the terminal freezes exactly 1 second before the test is scheduled to end without generating the dashboard. So I want to manually build the dash report from my log.jtl file using:<br><br> <code>./jmeter -g &lt;log file&gt; -o &lt;Path to output folder&gt;</code></p>
  
  <p>But when I run this command in terminal I get the error: <br><br> <code>An error occurred: Error while processing samples:Mismatch between expected number of columns:16 and columns in CSV file:15, check your jmeter.save.saveservice.* configuration</code></p>
  
  <p>The only thing I have in user.properties is (taken directly from <a href="http://jmeter.apache.org/usermanual/generating-dashboard.html" rel="nofollow noreferrer">http://jmeter.apache.org/usermanual/generating-dashboard.html</a>):</p>
  
  <pre><code>jmeter.save.saveservice.bytes = true
  jmeter.save.saveservice.label = true
  jmeter.save.saveservice.latency = true
  jmeter.save.saveservice.response_code = true
  jmeter.save.saveservice.response_message = true
  jmeter.save.saveservice.successful = true
  jmeter.save.saveservice.thread_counts = true
  jmeter.save.saveservice.thread_name = true
  jmeter.save.saveservice.time = true
  jmeter.save.saveservice.connect_time = true 
  jmeter.save.saveservice.timestamp_format = ms
  jmeter.save.saveservice.timestamp_format = yyyy/MM/dd HH:mm:ss
  </code></pre>
  
  <p>Running <code>./jmeter -g &lt;log file&gt; -o &lt;Path to output folder&gt;</code> with and without these additions to user.properties still causes the same error listed.</p>
  
  <p>Please help! </p>
  
  <p>UPDATE: When I run a test from nongui mode and it completes ('tidying up...' is printed to the terminal) as opposed to freezing, my dashboard generation <code>./jmeter -g &lt;log file&gt; -o &lt;Path to output folder&gt;</code> works correctly. So it seems the freezing problem lies in the test construction. The test ends by hitting a certain time of day, say 4:00 pm, which is added to the jmeter test in the thread group scheduler. Does anyone have any suggestions to how I can fix this? Has anyone experienced a similar problem?</p>
