We have a custom Python script that handles building out software (and uploading artifacts). I recently added a signal handler for handling aborted jobs. But, I am seeing inconsistent signals being sent. It LOOKS like Jenkins is sometimes sending multiple TERM signals (after 1 second).
Here are 2 outputs for the exact same job run about 10 minutes apart:

Those are just 2 examples. Other jobs had other interesting and inconsistent output. Sometimes, the signal handling routine is called 3 times.
I have attached the Python script for reference. (
(Note: I am new to Jenkins, so don't discount user-error. :/ )
