由于某种原因，我偶尔会不断收到此错误，而且我不知道如何解决。内存一直在说它已超出限制，这导致我的机器人不得不在我不希望的地方重新启动。这会导致机器人中的当前代码出现问题，而我不知道如何解决这些问题。有什么想法吗？
谢谢！

答案 0 :(得分：0)
使用Heroku免费层，您最多可以使用512MB。
要做的第一件事是在本地检查您的应用程序正在使用多少内存，然后进行性能分析/改进。使用NodeJS时，可以使用多种资源，其中一个有趣的博客是Understanding memory leaks in Node.js apps和Heroku NodeJS Memory use
要考虑的一个因素是Heroku的内存使用情况可能与您的本地实例不同，我遇到了这个问题，经过一些调整后，我无法再减少内存占用量（在我的情况下，我将应用程序移到了另一个云中提供商并解决了问题）。
