当我在heroku上托管messenger bot应用程序时，它运行良好一段时间但几分钟后崩溃，然后我必须通过cli再次重启heroku应用程序，有时它会自动重新开始工作。我不知道为什么会发生这种情况
这是我的procfile
web: node index.js
我已尝试了几种解决方案，但在几分钟后它仍然会崩溃。
喜欢
在cli
中输入此内容heroku ps:scale web=1
这就是我设置端口的方式
var app = express()
app.set('port', (process.env.PORT) || 5000)
// SPIN UP SERVER
app.listen(app.get('port'), function () {
console.log('Running on port', app.get('port'))
})

答案 0 :(得分：0)
如果没有看到完整的日志和完整的源代码，就无法确定，但有时服务会运行一段时间然后崩溃可能会泄漏内存或其他一些资源。仅仅因为V8为您处理内存分配/释放，不要假设您的应用程序不能泄漏内存。
如果它崩溃总是处理相同的请求那么它完全是另一回事，但是如果它处理请求然后崩溃没有明显的原因，你应该总是假设它可能是由于一些泄漏引起并更详细地研究它。 / p>
我担心，考虑到你在问题中包含的信息很少，没有人能告诉你任何事情。
答案 1 :(得分：0)
查看日志，实际崩溃的唯一时间后面会出现一个非常明显的错误：
