JMeter Issue

[Chandrashekhar Yavagal]

Hi Team,

I'm trying to load test for 2000 users with rampup of 60 seconds, getting error rates upto 54%, 

most of the time im facing below two issues :

Response code:Non HTTP response code: java.net.SocketException

Response message:Non HTTP response message: Connection reset

Response code:Non HTTP response code: org.apache.http.NoHttpResponseException
Response message:Non HTTP response message: 443 failed to respond

for some sampler results i will be getting below results

Response code:
Response message:Number of samples in transaction : 25, number of failing samples : 1

Response code:Non HTTP response code: java.net.SocketException
Response message:Non HTTP response message: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

Workflow: Attending for quiz & answer the questions.

User load: 2000

JMeter Version: 5.6.3

Configuration's: Intel 16 CPU, 50 GB RAM (available 4GB), 30 MBps Bandwidth

During load test we have observed that CPU load was just using 25% - 30% & RAM it was consuming max 2GB for 2000 user. 

Please let me know if anyone has any solution.

Thank-you

This is not a "JMeter Issue", given you're getting "failed to respond" it means that the system under test is overloaded and cannot properly reply to JMeter's requests.

Try increasing your load gradually and look into Active Threads Over Time chart and compare it with Response Times Over Time, Transactions Per Second and Response Codes Per Second

When you detect that response time is growing/throughput is going down or errors start occurring - check how many users were active just before that moment: this is the maximum your system under test can support without issues. If it's not sufficient - you will need to fix either configuration of the system under test or its code.

Ok Thank-you, I will try to increase load gradually & verify it, thank-you for your responce.
