一直在和我家用服务器上的一个奇怪问题作斗争：Docker 容器一开始能正常运行几个小时，然后容器内部的网络就会突然失效，但宿主机仍然有互联网连接。重启 Docker 可以暂时解决。有人遇到过这种情况吗，或者知道该从哪里开始排查？

Been fighting with a weird issue on my home server: Docker containers run fine for a few hours, then networking inside the containers just dies while the host still has internet. Restarting Docker fixes it temporarily. Anyone seen this before or know where to start debugging?
有人在把 Nginx 放在一个小型 Node.js API 前面之后遇到过随机的 502 错误吗？在本地运行一切正常，但在 VPS 上即使是轻度流量，上游偶尔也会超时。检查了日志也没有发现明显问题。不知道是不是和 keepalive 或 proxy buffer 有关。

Has anyone run into random 502 errors after putting Nginx in front of a small Node.js API? Works fine locally, but under light traffic on the VPS the upstream occasionally times out. Checked logs and nothing obvious. Wondering if it's keepalive or proxy buffer related.
