Graceful Network Socket Shutdown Timeout
You can use the Server Configuration Tool’s Channel settings to set the time interval for the server to execute a graceful network socket shutdown. In a graceful shutdown sequence, any data that has been queued, but not yet transmitted is sent prior to the connection being closed.
The Graceful network socket shutdown timeout setting allows you to define the shutdown time interval. If the time interval expires before the graceful shutdown sequence completes, an abortive shutdown sequence occurs, any unsent data is lost.
