我有一个python Apple MDM服务器，我试图将其从命令行进程转换为使用Nginx和uWSGI进行托管。我使用web.py进行路由。一切顺利，最适合的。我已经得到了我认为是Nginx和uWSGI的良好基本配置，但今天早上运行它不到24小时后，我在服务器收到的每个其他请求上都收到此错误。有足够的内存可用，我使用的是64位版本的python。
EDIT1：SSL正在端口8080上进行通信，因为它前面有一个负载均衡器，可以将SSL流量路由到该端口。
EDIT2：我已将uWSGI中的流程设置从3更改为1以查看是否存在问题。
EDIT3：这是来自AWS的新盒子。安装了我的服务器及其依赖项，nginx和uWSGI。我在运行uWSGI作为服务时遇到了问题，并且在我最终使aptitude版本与pip一起运行之前安装并卸载了pip和systemd版本。这就是它现在如何运行，它正常地停止，启动和重新启动。

答案 0 :(得分：1)
您的uWSGI .ini中没有设置max-requests。因此，您的python解释器永远存在并可能积累垃圾。尝试将其设置为某些内容，例如5000，希望泄漏会停止。
如果您将来获得更多统计结果，并且他们反对max-requests版本，请分享它们。祝你好运，James Fitter。
