What steps will reproduce the bug?

const { Socket } = require('node:net');

const socket = new Socket();
socket.on('error', (err) => {
  console.log(`error: ${err.code}`);
});
socket.on('connect', () => {
  console.log('connected');
});
socket.on('close', () => {
  console.log('closed');
});

setInterval(() => {
  socket.connect({ host: 'google.com', port: 5000 });
  setTimeout(() => {
    socket.destroySoon();
  }, 5);
}, 100);

How often does it reproduce? Is there a required condition?

It reproduces always. Port 5000 is chosen as it times out.

What is the expected behavior? Why is that the expected behavior?

Seeing an infinite stream of

error: ECANCELED

log lines

Comienza con el script de reproducción y los puntos de entrada de node:net indicados en los stack traces, especialmente Socket.destroySoon y Socket._final. Reproduce las conexiones canceladas repetidamente y, después, rastrea cómo se añaden y eliminan los listeners de finish y connect. Se considera terminado cuando el escenario ya no produce MaxListenersExceededWarning y existe cobertura para la regresión.
