Heroku上的Meteor应用程序会随着时间的推移而失败

我在Heroku上使用MongoLab附加组件（所有免费计划）托管我的meteor应用程序。随着时间的推移，应用程序将失败。我将无法登录（使用帐户包），继续收到

内部服务器错误

作为响应，没有其他有用的消息。要解决这个问题，我需要用heroku ps:restart重新启动dyno

但是在服务器端，这些错误会被记录下来

错误似乎是由于未能连接到数据库造成的。但这并不能解释为什么我必须重新启动应用程序，而不是数据库（在MongoLab）。

尝试从你的电脑连接到ML。你可能会在连接字符串中出错，或者服务已关闭。连接字符串是正确的。过了一段时间它才停止工作。数据库从未关闭，我可以手动访问它。我需要重新启动heroku以使其再次工作。在这种情况下，只有服务支持可以帮助您。
