Did you increase the timeout, what code are you using?

yes, but i have the same error, i'm using multiples example from mineflayer

const mineflayer = require('./mineflayer-1.13')

let i = 0
function next () {
  if (i < 100) {
    i++
    setTimeout(() => {
      createBot(`fabien-bot${i}`)
      next()
    }, 5000)
  }
}
next()

function createBot (name) {
  mineflayer.createBot({
    host: "localhost",
    port: 25202,
    username: name
  })
}

you might also want to disable all the plugins you don't need or go with nmp.

rom1504 commented 5 years ago

For a stress test mineflayer makes more sense actually, a nmp client will use less resources for the server (no physics / position sending)

Ok, can you try to increase the timeout ? I'm talking about the parameters you can pass to createBot

Hello, Sorry for the waiting time I've already try to increase checkTimeoutInterval but the issue is still here

Important : In 1.8.8 it's work perfectly

rom1504 commented 5 years ago

Ok, is your cpu at 100% for the process ? If so, spawn multiple process

rom1504 commented 5 years ago

1.9 and after are more cpu intensive to parse chunks. You can try to delay the connection of the bot so they have time to finish parsing chunks without overloading the cpu

rom1504 commented 4 years ago

Looks like it's solved
