Hello Christoph,
Thanks for the answer. I do indeed have more general problems with
ROCEv2: ib_send_bw works fine for ROCEv1 but not with ROCEv2. I'm
going to follow with the Mellanox persons as it seems to be mlx4 or
configuration-related.

Hi Marta,

Do you run with RDMA-CM?
Can you please provide the command lines you use and the GIDs table?

Hello Majd,
Yes, it's using RDMA-CM. I have re-connected the network and the machines have 
rebooted (unrelated panic) and now it's working fine. If I'm able to reproduce 
the problem, I will keep you updated.

Thanks for the help all,
Marta
