我正在 AWS Beanstalk 上部署一个 Ruby on Rails 应用程序。该应用程序还需要一个用于后台作业的sidekiq进程。还有一个正在运行的运动鞋进程来监听来自 RabbitMQ 实例的消息。
我使用此处概述的流程中的 ebextensions 为 sidekiq 创建了一个新贵流程。使用相同的大纲，我创建了另一个用于运行运动鞋 rake 任务的新贵进程。所有配置文件都在这个 gist中。
部署运行良好，我可以看到sidekiq 和sneaker 进程正在运行，但经过几次部署后，我开始看到正在生成许多占用数据库连接的rake 进程。

我不确定是什么产生了这些过程（如果是 sidekiq 或运动鞋或乘客）。随着每次部署，这个数字似乎会增加，直到 postgres 连接被最大化。
我的 beanstalk 配置不正确吗？谁能帮我调试一下，这样我就可以弄清楚是什么创建了这些进程？
