I can't get a network (I assume just TCP/20049 is fine, and not also some RDMA trace?) right now, but I will once a user has finished their work on the machine.

There wasn't any TCP traffic to dump on the NFSoRDMA Port, probably because everything is handled via RDMA/IB.
But I recorded a trace log of rpcrdma and sunrpc observing the situation.

To me it looks like the COPY task (task:15886@7) completes successfully?
The compressed trace.dat is attached.
