JS/TS Language Service repeatedly crashing

[mjbyrnes4664]

Type: Bug

I'm experiencing an issue with the JS/TS language service. The service is continually reloading and crashing rendering its features unusable. This service is expected to run silently in the background and provide intellisense for JS/TS files.

I have tried disabling all extensions and still see the issue.

Steps to reproduce

1. Open VS Code with a typescript project
2. Open a typescript file.
3. Notice the JS/TS language features load and intellisense works
4. Open a few more TS files
5. Switch between the open TS files
6. Notice the "Initializing JS/TS language features" is continually spinning in the bottom bar
7. Notice Intellisense will no longer work
8. Notice the pop up warning stating JS/TS language service has crashed 5 times

Versions

VS Code - 1.85.2 Node - 18.18.2 Typescript - 4.7.4

I have my project configured to use the workspace TS version, but also saw the issue when using VS Code's version (5.3.2)

Looks like the issue is due to the size of the project I have. I may have fixed it by giving tsserver more memory. Will report back next week with results. So far it's looks good

In settings.json

// 8GB of memory
"typescript.tsserver.maxTsServerMemory": 8192,
// custom node installation to allow more than 4GB memory
"typescript.tsserver.nodePath": "node",

Hmm. same issue

@digitalmaster in my case, the extension CodeGeeX cause this issue, you can check your installed extensions

[mjbvz]

From the logs, it looks like a memory usage issue. This can sometimes happen for very large projects. If your project isn't that large though and is still causing this crash, please open a new issue against typescript so we can investigate

Switching to use your own node version is the right workaround here as unfortunately our built-in node version is limited in how much memory it can use

[digitalmaster]

For me the issue went away by just setting the workspace version:
