I have this all setup using ConnectX-4 with IB/ISER but have no way of remotely creating the disconnect as I currently have it back-to-back. Have run multiple tests with IB and ISER hard resting the client to break the IB connection but have not been able to reproduce as yet. So it will have to wait until I can pull cables next week as that seemed to be the way you have been reproducing this. This is in a code area I also don't have a lot of knowledge of the flow but have started trying to understand it better.
