Description

bug needs repro

Type: Bug

Behaviour

Extremely frequently the VS Code remote attach debugger will not die when I kill the python -m debugpy ... process that is attaching to the port 5678. Until I restart the IDE I cannot start debugging again, because otherwise it will complain that "Python debugger is already debugging another instance". My colleaques haven experiened this issue as well, and it seems to be a recent regression (last couple of weeks).

As I wrote this, I cannot click the "Create on GitHub" button because VSCode is seeming unresponsive. I resolved by restarting the IDE.

Steps to reproduce:

  1. Use the below config for debugger
  2. Run python -m debugpy --wait-for-client --listen 5678 /path/to/module.py
  3. Run debugger
  4. Either detach debugger or CTRL-C the process on command line
