Error: Connection to server got closed. Server will not be restarted.

Issue Type: Bug

1. Clone the WebKit repo.
2. Generate a compile_commands.json file by starting a compilation with the -DCMAKE_EXPORT_COMPILE_COMMANDS=ON.
3. Set compileCommands to the path of the compile_commands.json file in .vscode/c_cpp_properties.json.
4. VS Code should start discovering and parsing files (as seen on the bottom-right of the status bar).
5. After some time (usually somewhere after 50% done), the error message will be displayed in the Output panel: "Connection to server got closed. Server will not be restarted." After that the C/C++ extension is restarted, and it has to reparse all the files. I don't think it has ever reached 100%.

If there's some more information I can provide, or some debugging steps you'd like me to follow (e.g. to provide a crash dump), please let me know. I couldn't find any additional instructions in the CONTRIBUTING.md file for this repo.

@mlalkaka, your report looks good, and we've tagged it for investigation. Sorry we haven't gotten to it yet as we're putting the finishing touches on the next update.

I have the same problem!

@azertyalex Is your repro with WebKit? Or some other repro steps?

Webkit

This is really breaking for me sometimes. Can I help in any way with the process of fixing this bug?

Any updates on this issue? This is also happening constantly on extension version 0.23.1 with vscode version 1.35.1 - loading a fairly large C++ project causes the "connection got closed" to appear every 5 or so minutes, and before that the CPU usage of Microsoft.VSCode.CPP.Extension.darwin (and some other similar/related processes) is insanely high (~90% CPU usage, and the fan is spinning like crazy on my MacBook Pro 6 core i9 32G). This is definitely making VSCode for C++ dev annoying to use - I was even considering alternatives (e.g. resorting to Xcode).

Please, can anyone raise the priority of this issue? It's a deal breaker!

Getting the same problem, but on Gecko instead of WebKit. No .vscode/c_cpp_properties.json though.
