Process Hangs On Jenkins Cancellation

[JamesMc86]

I have tried to cancel a jenkins job where LabVIEW was non-responsive.

I see that the LabVIEW thread is killed but something is hanging on in the application.

Log output:

Launching Program:
C:\Program Files (x86)\National Instruments\LabVIEW 2015\LabVIEW.exe "C:\Users\Public\Documents\National Instruments\LV-CLI Common Steps\steps\run-vi-tester.vi" -- -p:62908 "Monitor Software.lvproj" "test_results" "${WORKSPACE}"

LabVIEW started, process ID is 1152

Waiting for connection on port 62908

Thought I saw something similar so looked at the code more. If that is all of the output then it looks like the process tracking thread never stopped. We would expect "process tracking thread finished" in that case. Best check that there isn't a way to leave that thread running if the main process is terminated.

Not sure if it is related but if LabVIEW remains open and the CLI quits the tracking thread would hold on.

Added a line to close the tracking thread even if LabVIEW is still running in the instance that LabVIEW CLI has shut down.

Not seeing this any more - closing.
