There is nothing you can "increase", the error you got indicates that you received an incomplete response (2x times less than server stated it would be).

Most likely your server is simply overloaded so it cannot deliver the content in full. Check out your application under test logs - most probably you will find the reason there.

Other things to consider:

  • Set up monitoring of baseline OS health metrics on the application under test side, you can use JMeter PerfMon Plugin or SSHMon Listener for this
  • Enable profiler tool telemetry for your application for the duration of your test. The overhead should be minimal, however you will be able to collect a lot of useful information regarding slowest functions, largest objects, etc.
  • If there any middleware included (load balancers, transparent proxies, databases, etc.) they need to be checked as well as in n-tier system failure or slowness of a single component can lead to malfunction.
