Hi All,

For the very first attempt of MQTT Sub Sampler, Response code is shown as 200, but the received message is shown as 0. And all the remaining attempts of MQTT Sub Sampler are failing with Error Code 501.

Note : MQTT Pub Sampler is working fine for the same topic.

Don't use GUI mode for load testing !, only for Test creation and Test debugging. For load testing, use CLI Mode (was NON GUI): jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder] & increase Java Heap to meet your test requirements: Modify current env variable HEAP="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m" in the jmeter batch file Check : https://jmeter.apache.org/usermanual/best-practices.html
