Problem with WCF-Custom adapter (WS HTTP Binding with reliable messaaging) – Error event logged, even though transaction completed Sucessfully

I am using WCF-Custom (WS HTTP Binding) with Message security as Windows and using Reliable messaging in the send port. Its a static Port. 

Every thing works fine as expected for the interface. ie the transaction is success. After a min of the transaction completion. I am getting the following error

01. I have not checked Propagate Fault message (as a solution provided in another blog)

02. Its a static Port

03. I am using reliable messaging

The below error events are logged in the event viewer

The Message Engine Encountered an error while suspending one or more Messages ( ID 5677)

Event  ID : 5796

The transport proxy method MoveToNextTransport() failed for adapter WCF-Custom: Reason: “Messaging engine has no record of delivering the message to the adapter. This could happen if MoveToNextTransport() is called multiple times for the same message by the adapter or if it is called for a message which was never delivered to the adapter by the messaging engine”. Contact the adapter vendor
