Vite does not release ports when the server is stopped (v20.0.0)

[ksdc-grantw]

Current Behavior

Vite is not releasing ports when the server is stopped. So when I start it again, it looks for the next available port, ie:

> nx run company-web:serve
> vite serve

Port 3000 is in use, trying another one...
Port 3001 is in use, trying another one...

  VITE v5.3.5  ready in 1689 ms

  ➜  Local:   http://localhost:3002/company

Expected Behavior

When stopping the server, the port should be made available again, so when starting again, the server is running on the same port.

Additional Information

I recently upgraded from 19.6.2 to 20.0.0 and didnt see anything in the release notes between those 2 versions that would explain this.

I created a fresh workspace for 19.6.2 and the bug did not occur.

Same issue. Pressing CTRL+C to stop the server does not stop the server.

[llong2195]

Same issues. The error occurs everywhere using the terminal. I use nx 19.8.4. Temporarily handle this error by using: npx kill-port <port>

After migrating to latest Nx (20.0.6 at time of trying) I cannot reproduce this. I could in v20. I opened a PR to your repo to migrate to latest: https://github.com/ksdc-grantw/vite-server-bug/pull/1
