You need to make sure that the terminal you run hdl_graph_slam in is still running when you use rosservice call hdl_graph_slam/... In other words, open a new terminal to run the command.

Without much context of what it's supposed to look like I can't help you much. It looks like there's a lot of doubled walls which means the automatic loop closure is probably failing. Try saving the bin file and using interactive SLAM to improve it.
