Vite dev server requests are stalled forever

Requests are stalled forever

The Vite dev server can appear to hang when the host environment hits file-descriptor or inotify limits under heavy request volume.

Requests are stalled foreverdevelopment servers

Observed message

Requests are stalled forever

Why it happens

  • The system file descriptor limit is too low for the dev workload.
  • Linux inotify limits are too low for the number of watched files.
  • The browser and dev server are generating more concurrent requests than the host can handle comfortably.

How to fix it

  1. Increase the soft file descriptor limit and retest the dev server.
  2. Increase the relevant inotify limits on Linux if file watching is constrained.
  3. Restart the browser and dev server after changing the host limits.
