Extension randomly gets stuck communicating with the IntelliSense process on Mac #4989
Description
Issue Type: Bug
I'm working with a fairly large C codebase (~75k lines of code), and the plugin stops working at random.
When it does:
- Code completion is not available
- File outline is not available
- Checking for errors/warnings stops working
- Quick fixes and function documentation remain on "loading..."
- Sometimes, CPU usage for the C/C++ plugin process goes up and remains high until I kill VSCode
Unfortunately it stops working rather randomly, so I am unable to pinpoint what exactly is causing it. Sometimes it works for hours without problems, sometimes it stops 5 minutes after opening the project. If it stops, it stops for all windows and all tabs. Restarting VSCode is the only solution I found so far.
If there's anything I can do to try and debug this, please let me know.
OS: macOS Mojave. It happens on both my MacBook at work and my older MacBook at home
