检测到可能的 EventEmitter 内存泄漏。 Discord.js

Question

While my bot was running while I was asleep this warning came up saying:

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 guildMembersChunk listeners added to [Client]. Use emitter.setMaxListeners() to increase limit

Now my bot is in a decent amount of servers, How do I fix this?

I looked around and saw this:

require('events').EventEmitter.defaultMaxListeners = 15; 

Would this be the solution?

Answer 1

A maximum of 10 listeners can be registered for any event by default . This limit can be changed for individual emitter instances using setMaxListener() method, and the value can also be set to Infinity by setting maxListeners count to 0 . Since you have set the limit to 15 and whenever the listener's count exceeds this limit you will see the EventEmitter memory leak detected error. Instead of setting it to 15 listeners set it to Infinity and see the behavior.

For example:

const { EventEmitter } = require('events');
const emitter = new EventEmitter();

//Setting the listeners to Infinity
emitter.setMaxListeners(0);

//To validate the number of listeners listening to event you may log the below line
emitter.listenerCount('eventName');
