Question

我将celery与rabbitmq一起使用，但我最近收到此错误sock.setsockopt(SOL_TCP, opt, val), [Errno 22] Invalid argument，
详细地说，

{1: 1, 2: 16396, 3: 0, 4: 60, 5: 10, 6: 9, 7: 0, 8: 30, 9: 0, 10: 81059, 12: 1}

kombu.exceptions.OperationalError: [Errno 22] Invalid argument

(6, 7, 0)是我print(SOL_TCP, opt, val)中添加的_set_socket_options的输出

在提到_socket.pi之后，我明白了：

6，SOL_TCP = 6
7，TCP_SYNCNT = 7（我认为......）
0，val

我所知道的全部内容，我认为它与系统设置有关，它与其他具有相同代码和包的系统一起使用。但我对TCP_SYNCNT知之甚少，感谢任何帮助！

BTW，这是我的环境

Answer 1

由集合net.ipv4.tcp_syn_retries = 1解决，有人将其设置为0，这可能意味着永远不会在syn之前发送ESTABLISHED。

celery worker raise sock setsockopt TCP_SYNCNT [Errno 22]参数无效
