jmeter HTTP response code: org.apache.http.conn.HttpHostConnectException,Non HTTP response message: Connection refused Error

Question

I am working to JMeter for testing the load.I am using Amazon Server.when I test the load to 400 Concurrent users, I am getting the error message

HTTP response code: org.apache.http.conn.HttpHostConnectException,Non HTTP response message: Connection refused

Till the 400 Threads Request, it is working fine and provide us the response.

We are using Xammp and apache server.Can anyone help me out?

Thanks Mitesh

In simple words your server capacity is 400 threads/users. I assume tuning was done on server side and JMeter best practices were followed — Nachiket Kate

Make sure that your Apache is configured to accept as many as 400+ concurrent users. Here are instructions on calculating and setting.
Make sure that your JMeter is configured to produce as many as 400+ concurrent users. Here is the guide on proper JMeter tuning.
Make sure that your Apache and JMeter systems are not overloaded and have enough spare CPU, RAM, Network and Disk IO, disk space, swap, etc. You can use PerfMon JMeter Plugin for monitoring systems health.
