Docker化Django项目调整静态文件权限后出现Gunicorn OOM问题求助

我用Docker部署了一个Django Web应用，之前遇到静态文件无法被应用找到的问题，误以为是文件权限错误，于是把当前用户组添加到根目录下的静态文件夹权限中，之后应用就无法正常运行了。

具体表现：
现在Gunicorn会输出内存不足（OOM）相关信息，这个问题是修改根静态文件夹权限后才出现的。目前应用负载很低，因此我怀疑并非实际内存不足导致的。

Gunicorn日志：

[2024-08-30 19:08:12 +0000] [1] [INFO] Starting gunicorn 23.0.0
[2024-08-30 19:08:12 +0000] [1] [INFO] Listening at: http://0.0.0.0:8000 (1)

[2024-08-30 19:08:53 +0000] [8] [INFO] Booting worker with pid: 8

当前权限配置（ls -l输出）：

-rw-rw-r-- 1 ash ash  757 Aug 30 20:17 docker-compose.yml
-rw-rw-r-- 1 ash ash  965 Aug 26 18:02 Dockerfile

Dockerfile #

# Step 1: Use an official Python runtime as a parent image
FROM python:3.9-slim

# Step 2: Set environment variables
ENV PYTHONDONTWRITEBYTECODE=1
ENV PYTHONUNBUFFERED=1

# Step 3: Set up working directory
WORKDIR /app

# Step 4: Install system dependencies
RUN apt-get update && apt-get install -y \
    python3-dev \
    libpq-dev \
    postgresql-client \
    build-essential \
    nginx \
    curl \
    && rm -rf /var/lib/apt/lists/*

# Step 5: Install Python dependencies
COPY requirements.txt /app/
RUN pip install --no-cache-dir -r requirements.txt

# Step 6: Copy project files
COPY . /app/

# Step 7: Set up database 
# RUN python manage.py makemigrations
# RUN python manage.py migrate

# Step 8: Collect static files
RUN python gs-python/manage.py collectstatic --noinput

# Step 9: Gunicorn command to run the app
CMD ["gunicorn", "--bind", "0.0.0.0:8000", "app-name.wsgi:application"]

nginx default.conf #

server {
    listen 80;
    
    location / {
        proxy_pass http://web:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /static/ {
        alias /app/static/; 
        autoindex on;
    }
}

目录结构说明：
我的目录结构中存在两个static文件夹，不清楚具体生成时机，大概率是配置静态文件时产生的，目录结构截图如下：

现在寻求帮助排查问题，解决应用无法运行的状况。
