Heroku 上的 R14（内存配额超出错误）

Question

我在 Heroku 上有标准的 1x dyno 用于 Rails 应用程序。 我已经使用命令将 puma web concurrency 设置为 1

heroku config:set WEB_CONCURRENCY=1

这是我的heroku日志

最初我使用的是 hobby dyno，但遇到了同样的问题，所以我转向了 standard1x，但还是一样。 我在我的 rails 应用程序中使用 heroku redis 作为 redis_cache_store。

Answer 1

R14(Memory quota exceeded error) 表示您的应用程序使用的内存过多。

从您上面的帖子很难确定导致错误的原因。 有几种情况会导致 Heroku 上的 R14（超出内存配额错误）。 其中之一是内存泄漏。在我以前的经验中，发生此错误是因为我的一个文件中有未完成的循环。我认为您应该检查您的应用程序是否没有遇到内存泄漏。
