jmeter java scoket exception

Question

I am running load test to read data from my application. My system is Jmete2.10 Java 1.6 Apache Tomcat

I am running a http request with 200 users with loop count 1.

It run's successfully some times but i get socket exception error for some of the users. I checked my application logs and there was not error. But Jmeter is showing this error

java.net.SocketException: socket closed
at java.net.SocketInputStream.socketRead0(Native Method)
at java.net.SocketInputStream.read(Unknown Source)

Answer 1

Well, Apache tomcat by default process only 150 ( if i remember correctly) concurrent requests. If you expect to serve more than that, you need to increase the limit

in order to increase it open up server.xml and add maxThreads="200" under your connector

follow the tomcat documentaion http://tomcat.apache.org/tomcat-7.0-doc/config/http.html
