Windows 2012 R2 closesocket()挂在侦听套接字上 [英] Windows 2012 R2 closesocket() hangs on listening socket
问题描述
我在生产服务器上的情况很奇怪.
I have a weird situation on a production server.
我们有一个使用C ++编写的网络应用程序，该应用程序通过使用IOCP编写的TCP来满足用户请求.
We have network application written on C++ which serves users requests by TCP written using IOCP.
两天前，我们对Windows 2012 R2进行了更新(它安装了最新的安全更新.以前的更新是6个月前).更新之后，当尝试停止服务时，我们在日志中看到服务器挂起以关闭监听套接字
Two days ago we did an update of Windows 2012 R2 (it installed latest security updates. The previous update was 6 month ago). And after the update when trying to stop the service we see in logs that server hangs on call to close listening socket
closesocket(session->listen_socket);
下一个停止网络系统的模式:
The schema of stopping the network system is the next:
-
PostQueuedCompletionStatus(m_completion_port，0，NULL，NULL);x工作线程数
等待所有辅助线程完成工作
Wait all worker threads finish their job
CloseHandle(m_completion_port);
closesocket(session-> accept_socket);
closesocket(session-> listen_socket);
这在过去4年中一直很好，但是在Windows 2012 R2更新后，服务器突然挂起，一直处于通话状态 closesocket(session-> listen_socket);
This was working good for the last 4 years, but suddenly after Windows 2012 R2 update the server hangs forever on call closesocket(session->listen_socket);
我还尝试过使用将LINGER选项设置为0超时来进行无效关闭的解决方案，但这无济于事.
I've alsi tried as a solution to set LINGER option with 0 timeout to make abotive closure, but it didn't help.
所有想法如何解决此问题或进行任何其他诊断?
All ideas how to fix this or make any additional diagnostics?
