Problem using turtlebot + kinect

edit

Good Morning! I'm facing some troubles to create an octomap using RGBDSLAM with kinect in a turtlebot, without GUI. Every time when i stop to capturing frames and send the data to octomap_server, something unusual happen, the octomap only contains the last frame captured. I've already tried to create the octomap with kinect only, and it worked! But running turtlebot + kinect i can't create a full octomap from the area.

My steps were: Running turtlebot roslaunch turtlebot_bringup minimal.launch

And the controls roslaunch turtlebot_teleop keyboard_teleop.launch

Running Openni roslaunch openni_launch openni.launch

And the rgbdslam / octomap_server roslaunch rgbdslam headless.launch roslaunch rgbdslam octomap_server.launch

After the capture ends i send data to octomap_server, and then run octomap_saver

PS.: I don't think the problem is related to the capture process, because the memory raises when the process starts and stabilize when it stops

Thanks for help!
