It shows scan match is not well, may be you are moving in long straight corridor or less laser scan rate or very fast moving vehicle.

I did manage to get the tutorial.launch running without any errors, but I still don't have anything showing on Rviz.

I was crowding my CPU too much, and was not giving mapsaver long enough. I shutdown some of the processes running on the CPU and everything worked ok.
