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

We are doing performance testing in Jmeter for our project. But we are getting following error Non HTTP response code: org.apache.http.conn.HttpHostConnectException/Non HTTP response message: Connect to :443 failed: Operation timed out
We are running 10000 users ramp ip period 100 seconds
I am getting Non HTTP response message: Connection reset error
I have 2 calls.
POST HTTP request
GET HTTP request: I am extracting the location from the response headers of the first POST call request.
NO cookies or request headers to send for 2nd request.
When I run it from JMeter and Taurus YAML locally, everything works fine.
Running on JMeter on the Taurus container through, it runs fine.
Running YAML through the Taurus container, I am getting the above error: ** Non-HTTP response message: Connection reset**
Test Configuration:
execution:
concurrency: 1
ramp-up: 3s
hold-for: 30s
Not sure where the problem Is?
I tried other options like setting JMeter properties and others, for example:
hc.parameters.file: hc.parameters
http.connection.stalecheck$Boolean: true
https.sessioncontext.shared: true
https.default.protocol: TLSv1.2
https.socket.protocols: TLSv1 TLSv1.2
Checked the jmeter.log and bzt.log file for any errors. But none was found.
We cannot say anything meaningful without:
Knowing your test configuration (how many users, for how long, what is ramp-up, what it time to hold the load)
Seeing jmeter.log file (preferably with debug logging enabled for HTTP components)
Seeing bzt.log file and/or console output, again preferably with verbose switch
Seeing your container and container management engine health metrics (CPU, RAM, Network sockets, etc.)
In your case Taurus acts as a wrapper for JMeter test and it has its extra cost, it might be the case the container doesn't have sufficient resources to run both.
In my production environment I got the following error in my server:
Cannot forward to error page for request [/api/validation] as the response has already been committed. As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false
org.apache.catalina.connector.ClientAbortException: java.io.IOException: Connection reset by peer
Now I created a client and produced 1000 thread every second to call this [/api/validation].
The error I got was
Exception in thread "Thread-9954" org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://localhost:7080/v1/name/validate": Timeout waiting for connection from pool; nested exception is org.apache.http.conn.ConnectionPoolTimeoutException: Timeout waiting for connection from pool.
Now I want to know is what is the cause of Connection reset by peer .
According to what I know is this error occurs when the client aborts the connection by sending the RST packet.
I set the socket Timeout of my client's rest template to 9000. I make the server sleep for about 15000 MS. Now shouldn't the server get Connection reset by peer as the server tries to send the response after 15 seconds and my client just waits for about 9 seconds. Shouldn't I get the error?
Also in the production environment the wait time (Rest template socket time out) for the client is set to about a 90 seconds ( more than the time the server requires to response). Why is the error being produced in the production?
I have 50 threads test in JMeter with multiple session but when I test it half of the threads is failed and I got this error Connection:
Response code: 500
Response message: Connection refused: connect Aborting action - session 656255658 was closed
Check 2 things:
are you sure you’re not reusing same session accross threads ? Are you correctly correlating the session id.
If issue only happens over some limit (not at 25 users for example, but at 50) then it’s a load issue or configuration limit on server side
A few weeks ago I wrote a small program which created a socket to an apache webserver and made a request.
Back then I did not know that this web server had a KeepAliveTimeout of 5 seconds.
After my first request I waited 1 minute. After this I wanted to reuse my first socket for another webserver request, but got an error.
From Beej's Guide to Network Programming I learned that if recv returns 0, then the other side has closed its connection:
Wait! recv() can return 0. This can mean only one thing: the remote side has closed
the connection on you! A return value of 0 is recv()'s way of letting you know this
has occurred.
My questions are now:
What does Apache send when the KeepAliveTimeout is over - a FIN or a RST packet?
I know that using a TCP connection for 2 unrelated HTTP requests like in this scenario might
not be the best thing. But in order to understand TCP more the next question is:
After my first successful http request, and before sending the next HTTP request over the same socket, would there be somehow a possibility to get informed about this keepalivetimeout TCPsocket termination of the server other than receiving 0 from the next recv() call?
It will send a FIN. If you write a request to the server after that, send() will return -1 with errno/WSAGetLastError() = ECONNRESET.
would there be somehow a possibility to get informed about this keepalivetimeout tcp socket termination of the server
Yes, by reading the proper response header parameter, namely Keep-Alive: timeout=delta-seconds:
'timeout' Parameter
A host sets the value of the timeout parameter to the time that the host will allows an idle connection to remain open before it is closed. A connection is idle if no data is sent or received by a host.
The value of the timeout parameter is a single integer in seconds.
A host MAY keep an idle connection open for longer than the time that it indicates, but it SHOULD attempt to retain a connection for at least as long as indicated.
As you can see, it's up to the host to decide. Given it only SHOULD try to keep the connection open as long as promised, but it isn't required that it does in order to conform to the spec, so the server might decide to close and reuse the connection to serve another pending client.
