POWhy does .Net Socket.Disconnect take two minutes?
text
Body
copied!<p>I am using .Net's socket class and I am using the following code:</p> <pre><code>socket.Shutdown(SocketShutdown.Both); socket.Disconnect(true); </code></pre> <p>This then blocks for exactly two minutes. I have specified true because I am going to reuse the socket immediately and re-establish the connection. Whether I have the Shutdown call in there or not it blocks for two minutes. The only thing I can do is pass false to disconnect. But I want to reuse the socket.</p> <p>Any ideas?</p> <p><strong>UPDATE:</strong></p> <p>I have read the codes. I have set the DontLinger option. It does not help.</p> <p><strong>UPDATE 2:</strong></p> <p>I have added a network trace as per request:</p> <p>Trace 1: Using the DontLinger option</p> <pre><code>System.Net.Sockets Verbose: 0 : [4668] Socket#5009246::Socket(InterNetwork#2) System.Net.Sockets Verbose: 0 : [4668] Exiting Socket#5009246::Socket() System.Net.Sockets Verbose: 0 : [4668] Socket#5009246::Connect(eee:nnnn#-2063562120) System.Net.Sockets Information: 0 : [4668] Socket#5009246 - Created connection from aaa.bbb.ccc.ddd.eee:nnnnn to www.xxx.yyy.zzz.:mmmm.
