Server Socket hangs in Close_Wait

The scenario is the following:
I am sending bulk of data to clients from my C# Server Application.
All of a sudden Data flow stopped, No data Update in Client Side and the port gets blocked.

When this occurs, the Server side symptoms are

  1. Close_Wait in that port (netstat)
  2. Operation Would block (Error code : 135) in Log.
  3. Unable to make a new Connection from client.
  4. Telnet Fails to that Port

Currently we restart the server whenever the issue arise. Obviously this is not a solution.

Can someone offer a solution for Server socket stuck in Close_Wait in windows server 2008? Any suggestion for this scenario would be appreciated gratefully.

Thanks in Advance.

CLOSE_WAIT means the peer has closed the connection and TCP is waiting for the local application to close the socket.

So close it.
