gunicorn 停止查找 wsgi 目錄

我用 nginx gunicorn 和 supervisor 配置了一個 django 應用程序。幾個月來一切都執行良好，直到今天。我沒有觸及任何配置文件，但不知何故，502 bad gateway當我嘗試訪問我網站的任何頁面時，我現在得到了響應。

Gunicorn 在這裡有問題，這裡是它正在輸出的日誌：

Traceback (most recent call last):
 File "/home/ubuntu/exo/lib/python3.6/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker
   worker.init_process()

ModuleNotFoundError: No module named 'inventory4'

我非常困惑，因為之前一切都執行良好！

這是我對 gunicorn 的 django 配置：

settings.py:

WSGI_APPLICATION = 'inventory4.wsgi.application'

在 wsgi.py 中：

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'inventory4.settings')

application = get_wsgi_application()

這就是我的 /etc/supervisor/conf.d/gunicorn.conf

directory=/home/ubuntu/exostocksaas
command=/home/ubuntu/exo/bin/gunicorn  --config /home/ubuntu/exo/lib/python3.6/site-packages/gunicorn/config.py --log-level debug --bind unix:/home/ubuntu/exostocksaas/app.sock inventory4.wsgi:application

autostart=true
autorestart=true
stderr_logfile=/var/log/gunicorn/gunicorn.err.log
stdout_logfile=/var/log/gunicorn/gunicorn.out.log


[group:guni]
programs:gunicorn

這是我在 gunicorn 包中的 config.py 文件：

BASE_DIR = "/home/ubuntu/"
sys.path.append(BASE_DIR)


bind = '127.0.0.1:8000'
backlog = 2048


import multiprocessing
daemon: True
workers = 20
worker_class = 'gevent'
worker_connections = 1000
timeout = 300
graceful_timeout = 300
keepalive = 300
inactivity_timeout=300
errorlog = '-'
loglevel = 'info'
accesslog = '-'
threads = 2

老實說，我剛剛對 django 應用程序進行了更新，所以這很奇怪，有人知道可能導致此問題的事情的線索或經驗嗎？

我現在正在考慮的事情可能是我的虛擬機出現負載問題，這會導致 gunicorn 崩潰嗎？這是我跑步時注意到的landscape-sysinfo

System load:  9.56              Processes:           135
 Usage of /:   80.7% of 7.69GB   Users logged in:     1
 Memory usage: 38%               IP address for eth0: xxx.xx.xx.xx
 Swap usage:   0%

這可能是問題嗎？

我找到了這個問題的解決方案，以防有人絆倒她，免責聲明^^我無法解釋為什麼它停止工作以及為什麼解決方案解決了這個問題。gunicorn 日誌中顯示的錯誤似乎是一種預設問題，真正的問題是無聲的。我懷疑是CPU問題。

我只是去了 /venv/lib/python3.6/site-packages/gunicorn/config.conf 並添加

threads = 2

它以前設置為 1，然後設置為 2 就可以了。我非常願意接受任何更好的解決方案，或者解釋它解決問題的原因。
