Jmeter shows error after request takes more than 15 seconds to execute

Question

I have been trying to run a jmeter test, but everytime if some requests take more than 15 seconds to execute than it shows it as an error and says "Target sever failed to respond". I have already set all the timeout in apache2, mySQL and php config to very high. For the jmeter file, the connection timeout is 30 seconds and Response timeout is set to 120 seconds. You can check in the image that all the errors are after 15 seconds and they are random as well.

Answer 1

Try to disable KeepAlive in HTTP Request.

If you need to have KeepAlive enabled, try this

1. In jmeter.properties file uncomment this line hc.parameters.file=hc.parameters and change this line httpclient4.retrycount=2
2. In hc. parameters file uncomment this line and set number of miliseconds to greater value(e.g. 30s) http.socket.timeout$Integer=30000

Take care! This strategy is very aggresive to server
