How do I solve Jmeter Error Connection reset?

I am running a performance test on a site using Jmeter. Using a load of up to 100 simultaneous users(Threads) the tests pass perfectly, trying to raise this load to 300 users (Threads) I get the following error:

Non HTTP response code: java.net.SocketException / Non HTTP response message: Connection reset

The error occurs in only 0.68% of requests (out of 2412 requests made by 300 users(Threads) only 2 requests generated this error)

I thought it was the maximum number of connections allowed on my server, I went to my application's webconfig and entered the following information: "Min Pool Size = 5; Max Pool Size = 500;". but still not solve the problem.

Does anyone know what I can do to not generate these errors?

Most probably it indicates a problem with your application, try checking:

  • application logs
  • application/web server logs and configuration
  • underlying operating system logs and networking configuration. also pay attention to number of open ports/sockets/handles (can be checked using either built-in OS monitoring tools or JMeter PerfMon Plugin)

If you're absolutely sure that there is nothing wrong with your test script and application and JMeter is configured to behave exactly like a real browser you can follow instructions from JMeterSocketClosed wiki page
