你并不孤单，@helmi。
我从 3.2.5 迁移到 3.3.0 时也遇到了问题（大量的 502、429 等），不得不降级回 3.2.5。
最近我尝试重新升级到 3.3.1，希望情况会有所改善。在某种程度上，情况确实有所改善。只是出现了大量的 502 错误，影响了所有用户。
我决定全力以赴，相信 test-passed，现在使用的是 3.4.0.beta3-dev（ 2099c33fa7 ），这是 nginx 错误日志偶尔会输出的内容：

尽管虚拟机有 8 核、32GB 内存和 500GB NVMe 硬盘，我仍然不知道导致 502 错误的原因是什么。
我们选择了一个大型虚拟机，因为我们的社区大约有 450 名活跃用户、585k 个主题和 2150 万个帖子。
