50% samples for same requests failing while execution of Jmeter script - performance

I am executing Jmeter script and 50% samples for same request are failing. I am not sure why this is happening. Can someone help me to understand if this due to our server issue or because of my Jmeter script.
Edited: I found out that some samples are not able to extract regex from previous sample due to which failure is occurred. Now I wanted to know why some samples can extract regex and some cannot?

Thanks everyone for you help. Issue is resolved when I updated user-agent in header manager for that particular request.

Jmeter report got unfinished data

hello im a newbie who trying learn and use Jmeter, i have a question
when im run my jmeter scripti got a data that seems like not finish yet, like in the picture, so when i try to make dashboard report it always said "cannot error errorlevel=1"
this how the report looks like
As a workaround you can just delete this "problematic" line with the incomplete metrics.
With regards to the reason - it looks like that JMeter test has been terminated abnormally, check out jmeter.log file for any suspicious entries.
Looking into column "M" - allThreads it seems that you're running the test with 2800+ virtual users, it might be the case you need to follow recommendations from 9 Easy Solutions for a JMeter Load Test “Out of Memory” Failure article and if JMeter still lacks resources consider going for Distributed Testing.

JMeter httpclient.timeout property not working

In continuation to working on this issue - JMeter test not stopping after duration ends in distribution mode
Using JMeter version - 5.4
I got a thread dump and figured out few threads are getting stuck on HTTP Requests.
The resolution figured out is to set timeouts for the HTTP Requests as mentioned here - Configuring response timeout in Apache JMeter
But I'm not the author of the test plan. Hence, the only way I could use is to set JMeter properties.
I've set the following in jmeter.properties (values are for local testing):
httpclient.timeout=100
hc.parameters.file=hc.parameters
os_sampler.poll_for_timeout=100
and in hc.parameters
http.socket.timeout$Integer=100
But unfortunately none of these are working.
The only timeouts working are the ones when I set them in Advanced Tab of HTTP Sampler of the test plan.
Do we have any platform recommendation to control this behavior (like some other setting or property etc.)? Or am I missing anything in the above mentioned properties?
Also, I do sometimes get this exception in response, but I highly doubt if this is related?
Non HTTP response code: java.net.BindException
Non HTTP response message: Address already in use: connect
Your steps are correct so it looks like a bug in JMeter, presumably a side-effect of this commit so you have 2 options:
Downgrade to JMeter 5.0 where this functionality is still working
Raise an issue in JMeter Bugzilla but you will need to wait until someone fixes it and then either for a nightly build or a new release containing this fix
Fix it yourself and contribute the fix to the upstream

Non Http Response code: url fail to respond Jmeter

Today i got issue Non Http Response code when run script on Jmeter. My script run over some steps (Login - view) but got this issue and have log that issue at NoHttpResponseException.
I'm using Jmeter version 3.3. And I think that maybe this issue from server side, not by my script.
Does anyone fix this issue before? Please support me to resolve it.
This status code is being returned when an Exception occurs during HTTP Request sampler execution. There are hundreds or thousands of possible exceptions and even more potential causes for them.
If it occurs only under the load - most probably it's a server side error and you need to check the application under test logs and monitoring software results to identify the cause
It might be something described in the Connection Reset since JMeter 2.10 ?
It might be the case your JMeter script is badly designed/implemented and you're sending garbage instead of proper HTTP request
So try to collect as much information as you can:
Application under test and JMeter logs (it includes any middleware such as reverse proxies, load balancers, databases, etc.)
Application under test and JMeter machines health metrics (CPU, RAM, Network, Disk, Swap)
Network layer information, i.e. HTTP Request and response details.
Also be aware that according to JMeter Best Practices you should always be using the latest version of JMeter so consider upgrading to JMeter 5.0 (or whatever is the current latest JMeter version available at Downloads page) as soon as it will be possible.

Performance Testing In JMETER

While doing performance testing using Jmeter for a script, the viewstate captured while recording the script and the Runtime viewstate (i.e obtained after running the script in Jmeter) for a particular transaction does not match. Hence, could anyone suggest any solution to resolve this issue and capture the viewstate?
Viewstate changes so you need to use the regular expression extractor to get this value from the previous page and pass to current. You can find some information on how to do this here:
http://wiki.apache.org/jmeter/JMeterTesting/ASPNETViewState
Another thread from the SQA forum:
http://www.sqaforums.com/showflat.php?Number=608116
Once upon a time I worked on JMeter. I really don't remember if I faced the issue. But, I have captured my learning here. You can probably take a look. Would be happy if it helps you.

jmeter latency problem

After deployment from the nightly build, the response time of logging into the page is sometimes very high (30mins to more than an hour). I know jsps need to be recompiled after redeployment. However, it only takes 5 secs to login through the browser. It'd be great if anyone has any advice. Thanks!
When they updated code, did they modify anything on the login page? I would recommend re-recording the login process and compare to the original. You may find your script points to the wrong server or is now missing a required parameter.
