I have a WCF service hosted by a Windows Service. It has a Publish/Subscribe relationship to zero to many clients within the network. The binding is net.TCP. The WCF Service provides a "Subscribe" method to the client so the client can register a callback handler. The WCF Service periodically calls methods in the callback handler of any currently subscribed clients.
The interface is defined (with abreviation) below:
[OperationContract(IsOneWay = false)]
void ReturnInitialData(
InitialData initialData,
CraneState recentState,
VerticalCraneState recentVerticalCraneState,
ThresholdState recentThresholdState,
StationaryStatusFlagsState recentStationaryStatusFlagState,
LightsState recentLights,
BarrierRiskState recentBarrierRiskState
);
When the service calls ReturnInitialData() with approximately 42000 bytes of data, it works fine. When the service calls it with approximately 70000 bytes of data it throws the following exception:
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 '00:10:00'.
This is the netTcpBinding configuration:

Any leads or pointers are welcome.
You may want to enable WCF Tracing and Message Logging, which will allow you to monitor/review communication to/from the WCF service and hopefully isolate the issue (which, based on the provided error message, may likely be a timeout issue.)
