JMeter hangs while stopping a test

Stuart Barlow Wed, 10 May 2017 01:46:34 -0700

Hi,

Every now and then when stopping a JMeter test from the GUI the pop-updialog that says "Shutting down all test threads. You can see number ofactive threads in the upper right corner of GUI. Please be patient".I did was I was told and was patient but 20 minutes have now passed andthe dialog hasn't gone away and doesn't respond when I click on the X inthe upper right corner. The GUI shows 6 / 10 threads are still busy.

The test is fairly simple. I just send some HTTP GET and POST requestswith JSON content. It's not easily reproducible as it only happens nowand then.

Here's the thread dump if anyone can spot any obvious clues as to whatwent wrong:
