I'm trying to perform load 15000 concurrent requests on my application server(linux red hat) which has 16 core and 32 GB RAM through 2 jmeter server(windows server 2012) with configuration of 16 core and 32 GB RAM and getting this error "Non HTTP response code: java.net.SocketException/Non HTTP response message: Connection reset"
I've already followed this link related to configuration but couldn't find any solution Java.net.SocketException connection reset error in .net application
First i was using single Jmeter server(Window server 2012) for 15000 request and i split this into two servers 7500 concurrent request each with configuration of 16 core and 32 GB RAM but getting same issue on "Non HTTP response code: java.net.SocketException/Non HTTP response message: Connection reset"
It is a socket issue on your server end.
Go to /etc/security/limits.conf
and update soft limit to a higher value.
For example:
vi /etc/security/limits.conf
set ulimit of soft and hard to maximum count

hi there i am trying to deploy laravel project on my deticated server which has two processors about 32 core and 128 giga ram
i am using apache longue as web server and using mpm winnt (this is the allowed mpm for windows
my problem is when i testing using jmeter i get about 90% of requests quicly but the rest requests take too long time to response and i can not understand why ??
it seems like those requests hold in queue but i really dont no why
my winnt conf is
<IfModule mpm_winnt_module>
ThreadsPerChild 1920
MaxConnectionsPerChild 1000000
</IfModule>
i am trying to get 2000 request per second
The target for us to achieve is 500 concurrent users.
We have tried running a test for 100 users over 3 machines. And it ran fine without any errors.
When i tried running the test for 150 or More users with same number of machines, i started getting the following response code
Response code:Non Http Response code:java.net.socketException
Response message:Connection Reset
I have also tried increasing the number of machines to 8 machines. Still it is of no help. Response time is also very high (156 seconds) for some of the requests.
When we checked the server logs to find out what could be causing this issue, No error logs were found there during the time of the execution.
I'm having a hard time finding out what could be the issue. The server side is ruling out if there could be an issue from their end.
Tried the following fixes from Jmeter side:
Increasing the heap size
Changing the retry count in user.properties file
Changing Boolean=True in hc.parameters file
Used HTTP Request Defaulters to change the implementation to HTTPClient4
CPU Config:
Intel (R) Xeon(R) CPU E5-2690 v3 # 2.60 GHz (2 Processors)
5 GB Ram
64-bit Operating System
The Connection Reset error means failed attempt to write to the socket which has been closed already, on TCP protocol level it means receiving a TCP RST
It might be the case JMeter is closing the connection prematurely as JMeter 5.0 had httpclient4.time_to_live property set to 2000 and if you're seeing response times > 2 seconds (and you do) most probably JMeter is closing the connection before getting the full response.
You can try increasing this setting to 60000 matches modern browsers default settings or even more to match your application response time (if you think 3 minutes is acceptable) or consider upgrading to JMeter 5.3 which has better default value.

I am running a performance test on a site using Jmeter. Using a load of up to 100 simultaneous users(Threads) the tests pass perfectly, trying to raise this load to 300 users (Threads) I get the following error:
Non HTTP response code: java.net.SocketException / Non HTTP response message: Connection reset
The error occurs in only 0.68% of requests (out of 2412 requests made by 300 users(Threads) only 2 requests generated this error)
I thought it was the maximum number of connections allowed on my server, I went to my application's webconfig and entered the following information: "Min Pool Size = 5; Max Pool Size = 500;". but still not solve the problem.
Does anyone know what I can do to not generate these errors?
Most probably it indicates a problem with your application, try checking:
application logs
application/web server logs and configuration
underlying operating system logs and networking configuration. also pay attention to number of open ports/sockets/handles (can be checked using either built-in OS monitoring tools or JMeter PerfMon Plugin)
If you're absolutely sure that there is nothing wrong with your test script and application and JMeter is configured to behave exactly like a real browser you can follow instructions from JMeterSocketClosed wiki page

I am getting 'Non HTTP response message: Connection timed out: connect' for some HTTP requests so I tried to set the connection/response timeout value to 2 minutes (which is more than the connect time required for failing HTTP requests). To do this, I updated "HTTP Request Defaults" and added 120000 as Connect and Response Timeouts.
HTTP Request Defaults timeouts
[
However, when I run the test again, the HTTP requests still gave the same error. The sample result is as follows -
Load time: 21007
Connect Time: 21007
Latency: 0
Size in bytes: 2212
Sent bytes:0
Headers size in bytes: 0
Body size in bytes: 2212
Sample Count: 1
Error Count: 1
Data type ("text"|"bin"|""): text
Response code: Non HTTP response code: java.net.ConnectException
Response message: Non HTTP response message: Connection timed out: connect
It looks like the timeout value I set in HTTP request Defaults is not getting used here. I also tried to set the value of httpclient.timeout=120000 in jmeter.properties but no change. Have I missed something?
Can somebody please help me with this?
Thanks.
Edit - I have multiple HTTP requests and each run, different requests time-out. Here is one of the HTTP requests -
Updates:
I tried changing the Timeouts values in HTTP Request Defaults to very low (2000) to see how HTTP requests work. In this case, I was getting different error for requests exceeding connection time of 2000ms -
Non HTTP response code: org.apache.http.NoHttpResponseException/Non HTTP response message: : failed to respond
So I think changing the timeout values is not affecting my original error -
Non HTTP response code: java.net.ConnectException/Non HTTP response message: Connection timed out: connect
What is the difference between these two message?
The issue seems more of a server configuration of connection timeout than client side configuration of connection timeout, though both must be configured appropriately.
Default connectionTimeout in tomcat server is 20 seconds. and you request is failed due to connection timeout at 21 seconds. so, though you configured at client side (120000) you must configure appropriately at server side as well, otherwise, server forces to close the connection attempt and raises Connect Timeout exception.
Reference:
The HTTP Connector (refer connectionTimeout attribute)
Recently I have faced the same problem and found that it is the default configuration in my OS (Windows). Check the following links for details:
Where does the socket timeout of 21000 ms come from?
Which is the default TCP connect timeout in Windows?
Shortly, based on articles mentioned in the links above, Windows uses 3000ms initial timeout (InitialRto setting) and does 2 retries with doubled timeout from the previous attempt (MaxSynRetransmissions setting): 3sec + 2*3sec + 4*3sec = 21 sec.
In order to increase this timeout you can set more retries with the following command:
netsh interface tcp set global MaxSynRetransmissions=3
