Javascript 唤醒侦听器（MaxListenerSexceedawerning）Node.js

我在节点应用程序中收到以下警告：

(node:245) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 wakeup listeners added. Use emitter.setMaxListeners() to increase limit
    at _addListener (events.js:260:19)
    at Connection.addListener (events.js:277:10)
    at Connection.Readable.on (_stream_readable.js:687:35)
    at Connection.once (events.js:306:8)
    at Connection._send (/mnt/app/node_modules/http2/lib/protocol/connection.js:356:10)
    at runCallback (timers.js:651:20)
    at tryOnImmediate (timers.js:624:5)
    at processImmediate [as _immediateCallback] (timers.js:596:5)

我理解在这个事件中发生了什么，监听器被注册的次数超过了默认的最多10个监听器。我知道我可以增加这个数字，但我不确定这是解决问题还是掩盖问题

这是在http2 node_模块中，但我不知道调用它的是什么

这是我的package.json：

  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node --trace-warnings ./bin/start"

}

你有没有找到解决这个问题的办法？我在同一个调用堆栈中遇到了同样的问题。不幸的是，没有，它从来没有导致任何重大问题，并且我的侦听器总数从来没有超过11，所以我就放手了。
