When the process is trying to register the buffer using ibv_reg_mr, it failes after registering some number buffer. We are using Mellanox Technologies MT27500 Family [ConnectX-3] cards. Reconfigured options are : 1) cat /sys/module/mlx4_core/parameters/log_num_mtt 24 2) cat /sys/module/mlx4_core/parameters/log_mtts_per_seg 7 Can anyone point out reason behind ibv_reg_mr fails ?
