当我尝试在heroku上查看我的页面时，我收到Application Error页面。这种行为完全独立我推送任何新代码。网站不时会崩溃。它通常会带来一些重载。
我的procfile如下所示：
web: python manage.py run_gunicorn -b 0.0.0.0:\$PORT -w 9 -k gevent --max-requests 250 --preload --settings=myblog.production_settings
，heroku logs的输出为：

这似乎与I posted about earlier类似的错误无关。如果人们认为它更好，我可以在那里发布。
答案 0 :(得分：0)
我非常不建议用gevent做--max-requests 250 - 这完全违背了首先使用它的目的：）
