"不能因为系统缺少足够的缓冲区空间，或因为队列已满&QUOT执行套接字上的操作; [英] "An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full"

问题描述

我已经写在C＃中的IP多播应用程序。它编译罚款，但在运行时这一行：

I've written an IP multicasting application in C#. It compiles fine, but at runtime this line:

sock.SetSocketOption(SocketOptionLevel.IP,
                     SocketOptionName.AddMembership,
                     new MulticastOption(IPAddress.Parse("224.100.0.1")));

引发未处理的插座异常：

throws an unhandled socket exception:

不能因为系统缺乏足够的缓冲空间，或者执行套接字上的操作，因为队列已满

An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full

我搜索在谷歌的错误，人提议移除3GB开关（我的操作系统是Windows 7）可能已启用。我这样做，但仍然得到同样的错误。可能是什么问题？

I searched for the error in Google and people have suggested to remove the 3GB switch (my OS is Windows 7) which may have been enabled. I did that, but still get the same error. What could be the issue?

推荐答案

这可能是端口耗尽。
当应用程序（S）使得在较短的时间内过多的出站连接或者不妥善处置传出连接 - 你用完了端口

It could be port exhaustion. When application(s) makes too many outgoing connections in short time frame or does not dispose outgoing connections properly - you run out of ports.
