Large Map Fail to load

[jeremy7703]

@koide3
I met the problem that interactive slam was killed when I am loading a new map about '1GB' that was dumped from hdl_graph_slam
So, I am wondering what in essence decides the size of map that interactive slam can load up to? And may I have your advice on how to solve this problem

(Also, this happens after the load map progress went to 100%)
I put the terminal output below for your convenience:
