Description Kishore Sahadevan 2019-03-06 22:07:49 UTC

I have used the __threadGroupName function to name the HTTP Request samplers

eg: ${__threadGroupName}-LC_homepage

Script worked fine and gave the sampler name as expected in the reports.

When I tried a STOP while the script was running for a duration, it gave the below error and continued till the end of the test duration. SHUTDOWN works fine
