使用workerman/rabbitmq 报错，应该怎么处理呢？

php test_rabbitmq.php start
Workerman[test_rabbitmq.php] start in DEBUG mode
------------------------------------- WORKERMAN --------------------------------------
Workerman version:4.0.33 PHP version:7.3.22
-------------------------------------- WORKERS ---------------------------------------
proto user worker listen processes status
tcp www none none 1 [OK]

Press Ctrl+C to stop. Start success.
^CWorkerman[test_rabbitmq.php] stopping ...

Warning: Unknown: Epoll MOD(1) on fd 7 failed. Old events were 6; read change was 0 (none); write change was 2 (del); close change was 0 (none): Bad file descriptor in Unknown on line 0

有两点建议：
1、建议给官方示例脚本弄个options的说明，不然很多人不知道自动设置账号密码
2、以上报错应该怎么处理呢？
