async.queue sometime not end task

[vtlong]

What version of async are you using? ^3.2.2 Which environment did the issue occur in (Node version/browser version) Node: >=12 npm: 6.14.11

Hi , I have problem with async.queue.

my example:

var queue = async.queue((infos, callback) => {
      var task = new MyTask(infos);
      task.on('task_done', (error) => {
           console.log('Finish processing task: ', infos.ID);
           callback();
      });

     tart.start();
}, 5);

• sometimes task doesn't remove from the queue when finished. I see ''Finish processing task: 12345' is printed in console, but when I check the items in queue.workersList() I see item.data.ID = 12345 still exists, and never remove from queue.

Anybody help me?

Thanks!

ps: sorry for my english.
