NetTcpBinding - Where is the 10 minute timeout coming from?

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :WCF


I have a long running WCF service operation.  Although I've tried setting a number of timeout properies, I still get a timeout after 10 minutes:

"The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:19:59.9290000'." (note - the timeout occurs after exactly 10 minutes).

Service side, when I start the services I am setting the following:

ServiceHost host = new ServiceHost(typeof(SalesLedgerService));

foreach (System.ServiceModel.Description.ServiceEndpoint se in


  se.Binding.ReceiveTimeout = new TimeSpan(0, 15, 0);
  se.Binding.SendTimeout = new TimeSpan(0, 15, 0);


Client side, I am using the ChannelFactory and set the operation timeout as follows:

NetTcpBinding tcpBinding = new NetTcpBinding(

Round off time to the nearest minute

How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

SQL 2008 timeout


I am recently getting a timeout exception when executing this method. This table stores images and it might be due to the size of the table. I have no idea! Help!

            chunk = br.ReadBytes(bufferLen)

ReadXML Timeout


I am reading an XML file from an external URL and putting it into a dataset that is the populates a repeater. This works fine when I run it locally, however on the published web site I receive A connection attempt failed because the connected party did not properly respond after a period of time error messages.

However, if i type the URL directly into a browser, I get the XML file almost immeadately which leads me to believe that I am going about this the wrong way or I need to some how to extend the timeout period.

Here is my code:

Protected Sub ButtonValidate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonValidate.Click
        If Page.IsValid = False Then
        End If

        TableCellVATSIMIDResults.Text = "<br />VATSIM ID Validation Results for <i>" & TextBoxVATSIMID.Text & "</i>"
        Dim DataSetVATSIMValidation As New DataSet
        DataSetVATSIMValidation.ReadXml("http://cert.vatsim.net/cert/vatsimnet/idstatus.php?cid=" & TextBoxVATSIMID.Text)


<asp:Repeater runat="server" ID="RepeaterVATSIMValidation">
                    <HeaderTemplate />

If I manually launch the command, it take 240 seconds for a successful résult. I found that this command use regasm.exe, witch take 3.5 Minutes just for help (regasm.exe /?)

Why does this query timeout in an application but not in Management Studio?

I have a query that looks something like this:   SELECT TOP 1 * FROM Customers c (NOLOCK) WHERE Key = (mykey) AND NOT EXISTS (SELECT 0 FROM Invoices i (NOLOCK) WHERE i.key = c.key AND i.Date > GETDATE() )   When I run this inside an (ODBC) application, it times out.   When I run it within SSMS, it works fine.  That might make you think its an application problem, but the timeout only occurs for one specific customer ... even in the application, it works fine for all other key values.    Any idea where I can even start looking for a solution to this?  Thanks.

Cannot timeout connections when a network outage occurs

Hi, We are running SQL Server 2008 in a mirrored configuration.  Client access is performed using the Microsoft JDBC 2.0 driver, configured to failover to the Mirror in the event the Primary database is unavailable.  Additionally, the client maintains a database connection pool using Apache DBCP's BasicDataSource.  During testing, we have found that the failover works flawlessly if either the primary Database is taken offline or the primary SQL Server service is stopped - attempts to use existing pooled connections to the primary database fail immediately and new connections are created to the mirror database. However, when simulating a network failure (by disabling the network interface on the SQL Server machine) things aren't so nice.  The client first attempts to use an existing pooled connection to the primary database.  At this point the client hangs for up to 15 minutes before failing with the following error: Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Connection timed out         at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:1368)         at com.microsoft.sqlserver.jdbc.SQLServerConnection.terminate(SQLServerConnection.java:1355)         at com.microsoft.sqlserver.jdbc.TDSChannel.r

WCF Client (netTcpBinding) does not connect to remote DNS on Vista and Windows 7

Hi, WCF Client (netTcpBinding) does not connect to remote DNS on Vista and Windows 7. With other OS like XP and Windows 2003, client connects to remote DNS properly. I got the following exception. Same client works in Vista and Windows 7 if service is available in local network. Following are the exceptions: <Exception> <ExceptionType>System.ServiceModel.EndpointNotFoundException, System.ServiceModel, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089</ExceptionType> <Message>No DNS entries exist for host icelive.theice.com.</Message> <StackTrace> at System.ServiceModel.Channels.DnsCache.Resolve(String hostName) at System.ServiceModel.Channels.SocketConnectionInitiator.GetIPAddresses(Uri uri) at System.ServiceModel.Channels.SocketConnectionInitiator.Connect(Uri uri, TimeSpan timeout) at System.ServiceModel.Channels.BufferedConnectionInitiator.Connect(Uri uri, TimeSpan timeout) at System.ServiceModel.Channels.TracingConnectionInitiator.Connect(Uri uri, TimeSpan timeout) at System.ServiceModel.Channels.ConnectionPoolHelper.EstablishConnection(TimeSpan timeout) at System.ServiceModel.Channels.ClientFramingDuplexSessionChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.CommunicationObject.Open(TimeSpan timeout) at System.ServiceModel.Channels.ServiceChannel.OnOpen(TimeSpan timeout) at System.ServiceModel.Channels.Comm

Increase timeout on Send Activity

I am using Send activity to call another Workflow service. I am getting the following error: The HTTP request to 'http://fulfillment.odp.skinit.com/OrderWorkflowService/AssemblyWorkFlow/ReleasePhysicalAssetsWithArt.xamlx' has exceeded the allotted timeout of 00:01:00. The time allotted to this operation may have been a portion of a longer timeout. How do I increase the timeout in the Send Activity? Thanks.

Warning users before Session Timeout

Hi, In my web application, I want to alert users 5 minutes before their session timeout. If the users want, they can either extend their session or ignore the message - in which case after session timeout they will be redirected to the login page (I'm also using forms authentication in my site, so have set the authentication cookie expire time to the session timeout). I know I can do the alert with window.setTimeout, but I want to get user's respond and refresh the page if they want a session extension. How can I do that, in which event and whether I can do this in C# code behind. And also, should I implement this in the base page or somewhere else? How can I implement the auto page refresh - should I use a hidden button and click it from Javascript? It's great if someone can give a sample code for this.
