JMeter 5.3 Issue with Blazemeter Parallel Controller

[solution...@gmail.com]

Hi All,

While testing Blazemeter Parallel Controller (0.9) with Jmeter 5.3 version for few https requests, we are getting the following exception -

java.net.SocketException: Socket Closed 

at java.net.SocketInputStream.socketRead0(Native Method)
at java.net.SocketInputStream.socketRead(SocketInputStream.java:116)
at java.net.SocketInputStream.read(SocketInputStream.java:171)
at java.net.SocketInputStream.read(SocketInputStream.java:141)
at sun.security.ssl.InputRecord.readFully(InputRecord.java:465)

....

We tried the same script on JMeter 5.2.1 or lower versions and it works without any changes/issues. Please note we identified that is is happening with only few specific https calls and not all https one. We modified the ssl socket protocol, or connect timeouts in 5.3 but to no avail. 

However if I change the parallel controller to transaction controller in JMeter 5.3, it is starting to work without issues.

Seem some conflict on newer version of JMeter vs BZM Parallel Controller in specific cases.

Could you please check and let me know the resolution.

Agreed, we have observed issues with this plugin in 5.3 as well. It appears it always allows only 1 request within the parallel controller and rejects remaining with below exception. 

[Benjamin Ruhlmann]

Hello, I encounter the same problem.

Downgrading to jmeter 5.2.1 seems to solve the issue.

[singhab...@gmail.com]

Attaching a parallel controller test for reference on the issue.

Please advise on the fix.

[Thomas Scott]

I am also having this issue with JMeter 5.3 + bzm Parallel Controller 0.9.  Java version is 1.8.0_261-b12 (64-bit).  Is there a known release date for 0.10?

[Nikola Aleksić]

Hello,

Andrey, Artem, or whoever is maintaining the project. Did JMeter plugins project still alive? If yes, someone could give any comment about this issue and let us know if/when we can expect any solution, soon. Four months have passed and still no answer... Thank you and best regards.

[Jose P Joseph]

Seeing a similar error in JMeter 5.4 and Parallel Controller 0.9.

Having the same issue on JMeter 5.4 :( 

Is there any fix/workaround?

[Guillaume Betaillouloux]

The plugin apparently used to work on a "hack" that has since been fixed:

https://bz.apache.org/bugzilla/show_bug.cgi?id=64618

It's unlikely that this plugin can continue to work in versions above 5.2

[Thomas Scott]

Version 0.11 of this plugin was released on 20210430 and may have resolved this issue, but I haven't verified.  Perhaps someone else on this thread has?  The documentation reads 'What's new in version 0.11: Fix parallel controller for JMeter 5.3+'.

[Brian Tully]

I'm still having this issue intermittently with the Blazemeter Parallel Controller and versions of JMeter 5.2.1, 5.3, and 5.4. In looking at the code repo at https://github.com/Blazemeter/jmeter-bzm-plugins/tree/master/parallel, it seems the lead dev no longer works at Blazemeter. So perhaps this has been abandoned by Blazemeter?

[Rocky Keshri]

Hi Team,

I am observing some other errors with parallel controller 

Situation 1 -
If i place a parallel controller inside in the end of transaction controller then transaction controller data will not display in aggregate report.

Temporary Resolving situation 1- 
Placing a dummy sampler after parallel controller ,then transaction controller data will appear in aggregate report.

But issue with  Temporary Resolving situation 1- 

if any issue arises in the sampler inside the parallel controller then he will skip the dummy sampler and again the same issue will arise [Transaction controller data will not display in aggregate report]

My Email ID - rocky13...@gmail.com

Any response would be really helpful.

Regards
Rocky

Hi Rocky13...@gmail.com

I'm observing the following stanza in the Parallel Controller's documentation:

Limitations

Parallel Controller does not support work with Transaction Controller so if used you can get an unexpected results. If you decide to use these controllers together familiarize yourself with already known problems that described in roadmap

and from the roadmap link:

If Transaction Controller put in Parallel Controller and option Generate parent sample is enabled in Parallel Controller and disable in Transaction Controller than you'll not see the result sample of transaction (with number of samples and fails in transaction) in parent sample of Parallel Controller

So could you please observe documentation one more time. You can also observe How to Use the Parallel Controller in JMeter article which might be a little bit more informative up to certain extent.
