I am not able to reproduce it from new starter project. Will keep monitor it for more information.

Due to the error report JavaScript heap out of memory, have you try enable low power mode by config "volar.lowPowerMode": true?

[bitrevo]

I just enabled volar.lowPowerMode and use vscode for around 1 hour, then I got the similar errors.

But this time no infinity message popup, I can continue use it without restart vue server.
Infinity message still popup when some action triggered, e.g. autocomplete, etc.

In order to exclude that WSL2 may have a memory leak problem, could your try to use volar on windows without WSL2 to confirm?

By default, the upper limit of the memory of a single node process is 2GB, here has related comment #862 (comment).

[johnsoncodehk]

I have a feeling this issue is with recent TS releases microsoft/vscode#140090.

I can not migrate the existing project environment from WSL2 to Windows (too much work), but I think the issue related to nodejs memory usage.

Reference to #862, I added the nodejs settings in my ~/.bashrc then restart vscode. Up to now, It is still working fine without any error message popup.

export NODE_OPTIONS="--max-old-space-size=4096"

Default settings, nodejs is using around 2GB.

> v8.getHeapStatistics()
{
...
  heap_size_limit: 2197815296,
...
}

After adjust the settings, nodejs is using around 4GB

> v8.getHeapStatistics()
{
...
  heap_size_limit: 4345298944,
...
}

Since there is no repo case I can't check if this is a volar bug, and there is already a solution, I will close this issue.

Hey folks, I know its not helpful to say "me too" but I'm encountering a similar issue when working in a monorepo. sadly restarting the language server or lower power mode does not fix it

[Uomfan]

may be too many project files in the workspace, or too many projects opened at the same time by vscode

[pattrickrice]

I really don't think "you're using it wrong" is the answer. Vetur doesn't do this. No other plugin I use crashes with OOM

[qbunia]

Same problem here. Waiting for fix

[johnsoncodehk]

Unfortunately I can't check this issue, if anyone can provide a repro case I will actively resolve it.
