Memory Leak with Image Optimization in Next.js Docker Environment

[adgsenpai]

Link to the code that reproduces this issue

https://github.com/adgsenpai/imageleakdemo

To Reproduce

1. Create a Dockerfile for the Next.js application:

   
   FROM node:21.1.0-alpine

WORKDIR /app

COPY package*.json ./ RUN npm install

COPY . .

RUN npm run build

EXPOSE 3000

CMD ["npm", "start"]

2. Build the image

docker build -t nextjs-app .

3. Run the docker container

docker run -p 3000:3000 nextjs-app

4. Access the application and observe the memory usage.

5. Enable image optimization by adding or ensuring the following in `next.config.js`:

module.exports = { images: { domains: ['your-domain.com'], }, };

6. Monitor the memory usage using Docker stats or any monitoring tool:

docker stats

### Current vs. Expected behavior

Expected Behavior:
The Next.js application should run without any significant memory leaks, maintaining stable memory usage during operation.

Actual Behavior:
The application shows progressively increasing memory usage over time, leading to high memory consumption and potential crashes.

### Provide environment information

```bash
Operating System:
      Platform: linux
      Arch: x64
      Version: Alpine Linux
    Binaries:
      Node: 20.11.0
      npm: N/A
      Yarn: N/A
      pnpm: N/A
    Relevant packages:
      next: 12.1.6
      react: 17.0.2
      react-dom: 17.0.2

Which area(s) are affected? (Select all that apply)

Image (next/image)

Which stage(s) are affected? (Select all that apply)

next build (local)

Additional context

Deployment Platform: Docker Reproducibility: The issue is consistently reproducible in the Docker environment. It does not occur when running the application locally outside of Docker. Browsers: The memory leak is observed regardless of the browser used to access the application, indicating it is not browser-specific. Environment: The issue has been specifically noted when running on Alpine Linux with the following setup: Platform: linux Arch: x64 Version: Alpine Linux

nextjs is a really great framework but it's really tricky to use if it's not vercel..
