Hi, Sophie, thank you for reply: noticed that you are referring to MOFED 3.3-1.0.4.0 -- while problem what observed on MOFED-3.3-1.0.0.0 -- upgraded the OFED distro and NFSoRDMA works fine on ConnectX-4 Lx now.
Original problem was observed on CentOS 7.2, 3.10.0-327.el7.x86_64, OFED 3.3-1.0.0.0 & ConnectX-4 LX NICs (server & client identical systems).
Thanks & Regards,
Philip Romanov
