Why isn't my complete map saving when I do Teleoperation with turtlebot?

I have been trying to build a map of my apartment using my Teleoperation with a turtlebot 2. The map seems to look fine on rviz initially but when I save and try to use it with autonomous nav the map is incomplete. It seems to be missing the narrower parts of my apartment like my hallway and kitchen.

There is not enough information. What algorithm for mapping? Which commands do you use to save? What does the map look like and what would you expect? Paths to the saved map? launchfile for map server?...

I am using gmapping slam_gmapping and rosrun map_server map_saver. The saved map has only part of my apartment. The saved part is the largest room in my house. The rest of the house (Hallway, kitchen) are missing.

can you post / upload the saved map somewhere as well as a screenshot of rviz where we see the map produced by gmapping?

I actually figure it out. The problems were that the map dimension params were set to be too small and that I was moving the robot too fast. If I let it sit for few seconds it mapped fine. But my new problem is that when I start AIML using RVIZ for autonomous navigation it isn't working to great.
