If you  have build the kernel IB user space support (uverbs) and the IB 
libs, do "ibv_devinfo" if not, just ossi "cat 
/sys/class/infiniband/mlx4_0/*" and send the output. To be clear, iser 
does work for you on the productive servers but not on this server?

As its local protection error on TX, I don't see how this could relate 
to the target node.
