WCF, The sequence has been terminated by the remote endpoint. The user of the remote endpoint's reliable session expects no more messages and a new message arrived. Due to this the reliable session cannot, WCF Reliable Messaging
We are using WCF reliable messaging but occasionally user's sessions are dropping. The error message that is being generated is as below. I can't find reference to this specific error message anywhere. Does anyone have any insights into this issue or have diagnosed this error message before. It sounds like there is a sequencing issue but I am not sure. In terms of config, our endpoint bindings match up ok, and I can't see any obvious issues. If there are any Microsoft people online, can you explain the error as there appears to be no documentation for it anywhere.
