“An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full” after long run when server down #13102
Description
os: win server 2012
grpc version:1.6.1
.net framework:4.5
I run the following code for about two days . In this test, i doesn't start the server, after two days, every application on the machine can't establish outgoing tcp connect.
every time you want to build a new outgoing socket, a errors like this throwed.
“An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full”
if we close the grpc client, other application can establish new tcp connect.
and there may have memory leak . because my server and client need about 10mb more every day.
issues #13088 is about memory leak.

Channel channel = null;
try
{
channel = new Channel("192.168.163.14:50051", ChannelCredentials.Insecure);
var client = new Greeter.GreeterClient(channel);
//since the server doesn't start, this will throw exception
var reply = client.SayHello(new HelloRequest());
Console.WriteLine("Greeting: " + reply.Message);
}

Console.WriteLine(ex);

//the smaller sleep time,the quicker problem occurs
Thread.Sleep(15000);
