2.2.29 mlx4_ib Insertion Error when RDMA Starts

You can safely ignore the following error when the Oracle-supported RDMA service starts:

Loading OpenIB kernel modules:insmod: error inserting  
'/lib/modules/3.8.13-69.3.4.el6uek.x86_64/kernel/drivers/infiniband/hw/mlx4/
mlx4_ib.ko': -1 File exists

The message indicates that the mlx4_ib module is already loaded.
