Node process on Windows 11 consumes memory continuously, increasing about 3mb a second without being released

[scotscoder]

Description

When running wails dev, the node process gradually consumes more and more memory, slowing down the host system. As observed, it increases by about 2.5 to 6mb per second on my system. GIF attached.

This happens with a completely new Svelte project. I will test it with other JS frameworks as well and update this issue.

To Reproduce

Use Windows 11.

1. Init a new wails project using Svelte
2. Run wails dev
3. Watch the memory increase in Task Manager

Expected behaviour

Memory use should stay constant or "breathe" slightly up and down.

Attempted Fixes

Found a closed bug on the SvelteKit repo that mentioned a similar problem. It may be upstream from even that, but I'd rather check before we dive deeper.

Additional context

No response

I only noticed this issue because it started increasing my laptop fan when it reached 5GB of RAM consumed.

[scotscoder]

This is after 30 minutes.

It does seem to partially garbage collect periodically, just not very much.

Sounds like an issue with Vite. Have you tried upgrading it?
