[yanwi]

Hi, I use your plugin and when I test always got this, I still using gui, when got this error, still can hit another
But when I use cmd, always got this error so I cannot load test

SEVERE: ~* Channel ManagedChannelImpl{logId=1, target=10.27.2.204:6790} was not shutdown properly!!! *~
Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

Hi @yanwi, please help me check that the request already hit on server or not?
For the error above, I think that you force terminated the process by press Ctrl+C on command line, and the gRPC connection was interrupted.

• If the request hit your server, the error above seemly cause annoyed but it still worked then I will update the plugin by add the listener to close connection when catch a signal (IPC) in future.
• If the request can be not deliver to your server, seemly the plugin got an bug.
  Please response to me!

Thanks & BR

Hi @thoainguyen,
If the request hit your server, the error above seemly cause annoyed but it still worked then I will update the plugin by add the listener to close connection when catch a signal (IPC) in future. -> already received on my server

So the architecture of my test like this
jmeter -> service a -> service b

Message received on service a & service b

What confused me is because it works on gui but got that message, but when i test on cmd it doesn't work

For the error above, I think that you force terminated the process by press Ctrl+C on command line, and the gRPC connection was interrupted. -> I didn't do this, it happens when I'm test
