mongodb - meteor 应用程序崩溃随机抛出 'MongoError: server instance pool was destroyed'错误

Question

我使用mup将 meteor 应用程序部署到AWS服务器，该服务器使用docker部署了该应用程序。我还使用了mLab沙盒数据库。

问题是，一段时间后，应用程序崩溃而没有警告。崩溃意味着该应用程序仍然可以运行，但不会从数据库中加载数据。我有两个版本的应用程序(登台版和正式版)在两个不同的服务器上运行。但是两者都有这个问题。在docker日志中，我看到此错误重复了很多次:

知道发生了什么事吗？

在客户端浏览器控制台中，我看到此错误:

WebSocket connection to 'wss://oursite.com/sockjs/373/2lrpal10/websocket' failed: WebSocket is closed before the connection is established.

更新npm-mongo和mongo为我解决了这个问题。

meteor update --all-packages
