Unable to watch too many open files and memory usage not freed up

[thoriqadillah]

Version: Deno 2.0.0 I tried to play around with deno 2.0 by running my nest js project. In nest js, we can watch the file changes during development, and i found deno cannot do the script. here is the error

[4:27:07 PM] Starting compilation in watch mode...

[4:27:19 PM] Found 0 errors. Watching for file changes.

error: Uncaught Error: Too many open files (os error 24)
    at new FsWatcher (ext:runtime/40_fs_events.js:24:17)
    at Object.watchFs (ext:runtime/40_fs_events.js:74:10)
    at ext:deno_node/_fs/_fs_watch.ts:57:21
    at callback (ext:deno_web/02_timers.js:68:7)
    at eventLoopTick (ext:core/01_core.js:210:13)

and then i tried to ran it without the watcher by running deno task start, and the memory usage was not going down, and stucked in about 900 MB. when i ran it using node, the memory usage also went up to ~1 GB, but it went down some seconds later, but not with deno.

i found that deno is running node to make the script works, and i thought its kinda interesting. here is the screenshot

Same issue as https://github.com/denoland/deno/issues/26071 and https://github.com/denoland/deno/issues/17757

Same issue for me. Tried running deno run dev in my Vite + Vue project, but got hit with Uncaught Error: Too many open files (os error 24) right away. Same thing happened with my Astro app. This is on WSL (Ubuntu 22.04), but no issues on macOS.
