java.io.IOException: Premature EOF

Answer 1

Most probably it indicates the problem with the SUT itself, ie you're receiving a response in chunked format and not all response parts could be downloaded.

1. Inspect your application logs for any suspicious entries
2. Make sure that the system under test has enough headroom to operate in terms of CPU, RAM, Network, Disk, Swap, etc. - this could be done using JMeter PerfMon Plugin or SSHMon Samples Collector
3. Make sure your HTTP Request configuration exactly matches the request which is being sent by the real browser, ie you might need to add a HTTP Header Manager and configure it to send all the headers which real browser is sending.

If you're absolutely sure that the problem is not on your SUT end you can try switching "Implementation" for your HTTP Request samplers to HTTPClient4 , this could be done at "Advanced" tab of the HTTP Request sampler
