java.net.SocketException: Connection reset on reaching 3000 users in JMeteR

Question

All required changes have been done to respective files like:

• stalecheck=true,
• keepalive is checked from HTTP request defaults,
• retrycount=1,
• hc.parameters file changes,
• Socket timeout is 240000

Still we see "java.net.SocketException: Connection reset" in response data however I see the valid requests been passed to Server.

The issue wasnt till we reach 3000 users, worked smoothly till 3000 users.

Answer 1

Connection Reset has a lot of meaning, possible reasons are:

• One of the server components is not able to handle load so it closes connections on its side

• On JMeter side, check that you running in NON GUI mode and that neither JMeter JVM nor injector machine are overloaded which could explain this. See:
