Starting multiple firefox instance in jMeter, some of them don't operate - jmeter

I start a load test for a web application with 25 threads in 60 seconds in 1 loop. The test consist of some selenium commands. When the test start jMeter start 25 Firefox windows but some Firefox windows do not execute the commands and remain blank.

Are you sure your system is capable of running 25 browsers? Looking at Firefox browser version 92 system requirements:
Recommended Hardware
Pentium 4 or newer processor that supports SSE2
512MB of RAM / 2GB of RAM for the 64-bit version
So do you have 51 GB of RAM an 26 CPU cores? It doesn't seem so as some of your browse instances don't respond to JSONWire protocol commands
Looking into WebDriver Sampler Introduction:
Note: It is NOT the intention of this project to replace the HTTP Samplers included in JMeter. Rather it is meant to compliment them by measuring the end user load time.
So you're supposed to be creating the main load using JMeter's HTTP Request samplers and if you want to additionally test the frontend - use 1 or 2 browser instances. There are several ways of converting Selenium scripts into JMeter test plans.

Cannot record requests because of Certificate Errors

lately I changed my PCs and right now I am using M1 MacBook Pro and Lenovo ThinkPad (Windows). On Firefox, I configured my proxy and certificate setting just as I did with my previous computers. But when I try to record the traffic of targeted websites, I receive different certificate and SSL errors. I see the requests on View Results Tree and Recording Controller, but i get the following errors:

And on Sampler Result tab it shows me this warning:
ensure browser is set to accept the JMeter Proxy certificate
And how I configured Mozilla Firefox and JMeter:
Added localhost with 8888 port as my proxy
Added Jmeter Proxy certificate into my certificates
Made sure that JMeter is set to 8888 port.
Waiting for your help :)
Your configuration seems valid to me so I can only think of possible bug in Java runtime like JDK-8213202
So you might want to try i.e. Azul Zulu Builds of OpenJDK for arm-64 and see whether it resolves your issue.
Alternatively you can consider using JMeter Chrome Extension, in this case you won't have to worry about proxies and certificates

How can I solve a time out error in Jmeter

I am working with load testing in Jmeter and Blazemeter and I apply it in two different versions of the web application. One is the test version and the other is the production version. My script works fine in test version but not in the other one. Here I get some petitions that throw errors like this:

I am new to jmeter. I do not know how to solve this. Maybe it is not an error of my script. Still... do you have any suggestions?
Thanks
Most probably you're running into situation described in Connection Reset since JMeter 2.10 ? article from Apache JMeter Wiki
According to the article the reasons could be in:
Retry or stale check can hide issues on Server configuration:
Server failing to send the (optional) Keep-Alive header
Overwhelmed server refusing connection, retrying would increase load
So I would recommend
to check whether your production version is really sending Keep-Alive header in particular and compare the response headers from test and production environments in general:
to ensure that the application has enough headroom to operate in terms of CPU, RAM, Network sockets, etc., it can be done using i.e. JMeter PerfMon Plugin
If you're absolutely sure that your application behaviour is correct you can amend JMeter properties as it's described in the Wiki page to tolerate potentially incorrect system under test setup.
In user.properties file add the next lines:
httpclient4.retrycount=1
hc.parameters.file=hc.parameters
In hc.parameters file add the next lines:
http.connection.stalecheck$Boolean=true

Unable to launch slave in JMeter 4.0

I want to do the JMeter Master Slave setup in JMeter 4.0 in Windows OS.
I have done the following change in the jmeter-server file.
RMI_HOST_DEF=-Djava.rmi.server.hostname=10.304.61.62
To launch the slave I execute the following command from the bin folder
jmeter-server
This is working in JMeter 3.1. But getting the following error in JMeter 4.0

According to Setting Up SSL chapter of the Remote Testing JMeter User Manual entry you need to do one of the following things:
If you want to use secure communication between master and slaves you need to launch create-rmi-keystore script (it's located in "bin" folder of your JMeter installation) - it will produce the required rmi_keystore.jks file.
If you don't want to use secure communication between master and slaves you can add the next line to user.properties file
server.rmi.ssl.disable=true
JMeter restart will bre required to pick the property up
No matter of the approach you will have to implement either 1 or 2 on master and all the slaves
The above answer is based on JMeter Distributed Testing with Docker article.

JMeter - Getting Exception while running JMeter via GUI

I am trying to set up an aws server for performance testing of APIs where the logs will come. I installed Java and Jmeter on that server.
The application server is different i.e. test.server.com:8080
The aws server is different with different ip address.
The Jmeter GUI is installed on my laptop.
In my system in the apache Jmeter --> bin folder --> jmeter.properties, I have defined remote_hosts as ip address of the aws server where the logs should appear.
And server.rmi.localport=50000
I have not made any changes in the jmeter.properties file that is installed on aws server where the logs of performance testing should come.
When I run the Jmeter UI from my system and run --> remote start -> select the ip address of the aws server, it gives me connection time out exception.
In Logs am getting :

There is some configuration which has not been correctly done I believe. How can I check and what all changes should I make to run the test scripts.
Looks like network/firewall issue. Master & slaves should be in same subnet. If possible, you could create another instance in AWS and make it as a master. Ensure that jmeter master, slaves are able to talk to each other.
You might be behind the firewall. You can access AWS. But AWS can not access your machine/or the application behind the firewall.
Check if you are able to telnet through the specific port.
check AWS inbound/outbound rules.
If you use AWS, I would suggest you to use dokcer + rancherOS - It makes my life much easier in jmeter infrastructure setup.

I searched for this error and got that i have to download winutils.exe which i did, I set the path HADOOP_HOME = "c:\Hadoop" and then ran the command
C:\Hadoop\bin\winutils.exe chmod 777 /tmp/hive
but i got following error
This version of C:\Hadoop\bin\winutils.exe is not compatible with the version of
Windows you're running. Check your computer's system information to see whether
you need a x86 (32-bit) or x64 (64-bit) version of the program, and then contac
t the software publisher.
I tried to search 32 bit version of winutils.exe but i couldnt get it.. Please help me with this installation.
Thank You in advance
