bind: address already in use

Bug report

• I confirm this is a bug with Supabase, not with my own application.
• I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

supabase start fails randomly due to a port already being in use. It seems to be a timing issue as it only happens every other time when running the Github Action below.

This is the error generated:

Digest: sha256:48d2fabef1b0b1e8f9b208518008686a1cd336503af4fd6f62e169268ed9066e

Try rerunning the command with --debug to troubleshoot the error.

To Reproduce

1. Create a Github Action

name: "Push migrations"
on:
  push:
    branches:
      - main

jobs:
  test:
    runs-on: ubuntu-latest

    permissions:
      # Required to checkout the code
      contents: read
    env:
      SUPABASE_ACCESS_TOKEN: ${{ secrets.SUPABASE_ACCESS_TOKEN }}
    steps:
      - name: Checkout repo
        uses: actions/checkout@v4
      - uses: supabase/setup-cli@v1
      - name: Link Supabase project
        run: supabase link --project-ref ${{ vars.SUPABASE_PROJECT_ID }} --password ${{ secrets.SUPABASE_DB_PASSWORD }}
      - name: Start Supabase
        run: supabase start
      - name: Push migrations
        run: supabase db push --password ${{ secrets.SUPABASE_DB_PASSWORD }}

2. Run the action

Expected behavior

I expect this action to run successfully every time.
