Message is not allocated to specific thread when running multiple thread JMeter websocket plugin

I run the JMeter websocket with 10 threads and use While Controller to read message by using WebSocket Single Read Sampler. However, my expected data for thread 10 has been read in thread 9 so my loop cannot end. How can I sort this issue out?

We cannot suggest anything meaningful without knowing how the "messages" are being handled by the backend, blind shot: your correlation or parameterization fails somewhere somehow and multiple threads are connecting to the same session so the server responds to "wrong" thread as it is not able to distinguish the connections.

Double check all outgoing message details using Debug Sampler and View Results Tree combination, it might also be a good idea to enable debug logging for WebSocket Samplers plugin by adding the next line to log4j2.xml file:

<Logger name="eu.luminis" level="debug" />

and upon JMeter restart you will see many more details in jmeter.log file
