Language server doesn't stop when quitting VSCode (Linux)

[sporto]

I noted that after quitting VSCode the language server keeps running on the background.

Expected Behavior

Stop the server process

Current Behavior

I open VS code, the LS starts. Then I quit VS Code but the LS keeps running. Doesn't happen all the time, but often enough.
I have to kill the process manually.

Steps to Reproduce (for bugs)

• Using Ubuntu 21.04
• Open VS code, edit Elm code for a while
• Quit VS code

Your Environment

• Version used: 2.2.0
• Editor name and version (e.g. VSCode 1.36.1): VSCode 1.58.2
• Environment name and version (e.g. node.js 5.4): node 14.15.1
• Operating System and version: PopOS 21.04 (based on Ubuntu 21.04)

Is the editing still working for you at that point in time?

@razzeee I don't understand the question, sorry. Maybe I wasn't clear. After quitting VS Code the elm language server still keeps a process running. I would expect that quitting VS code would kill the lsp process. Happy to provide more info and help.

It would be interesting, if you could still use the lsp before that. If it was already stuck on something at that point, it might explain, why it misses the shutdown.

I can confirm that this happens when the LSP stops responding.

I don't know how it gets into this state, it appears that this happens when I change things too quickly, but unsure. I notice this when the LSP stops formatting my code on save.

Then if I quit the node process keeps going and I need to kill it manually. So the cause of the issue that the LSP becomes unresponsive.

Yeah, that's going to be harder to track down, but good, that we can narrow it down.
