Zombie processes hogging CPU/RAM, Duplicate diagnostics #24828
Description
Type: Bug
I'm putting this out here as a feeler, as I have no info on the bug
Behaviour
Over the past few days, vscode has been unusable for Python development.
Some things I am noticing are:
- Several python processes using significant CPU/RAM
- Some of these python processes show no parent process
- Duplicated diagnostics from pylance, mypy, flake8
Steps to reproduce:
Unsure about this, it seems to happen every time, but especially when doing work with CDK
npx cdk init app --language python- Set interpreter
- Start editing
Diagnostic data
Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
