rtabmap stops recording images after 7-10 seconds

edit

I am having on ROS Kinetic on Ubuntu 16.04. I am trying to run Kinect 360 on ROS to get regular as well as depth images. I have installed freenect and rtabmap using following commands.

sudo apt-get install -y ros-kinetic-freenect-camera ros-kinetic-freenect-launch
sudo apt-get install -y ros-kinetic-freenect-stack ros-kinetic-libfreenect
sudo apt-get install ros-kinetic-rtabmap-ros

Now, in CASE 1. running roscore in 1st terminal then launching freenect in 2nd terminal.

roscore
roslaunch freenect_launch freenect.launch depth_registration:=true

In 3rd terminal launching rtabmap.

roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start"enter code here

the rtabmap window opens but it doesn't record any images and in the freenect terminal window the following oputput repeats.

[ INFO] [1556638758.135309207]: Stopping device RGB and Depth stream flush.
[ INFO] [1556638780.594793009]: Device timed out. Flushing device.
[ INFO] [1556638780.595096944]: Starting a 3s RGB and Depth stream flush.

and in rtabmap terminal the following warnings repeat.

[WARN] [1556639251.666465373]: /rtabmap/rgbd_odometry: Did not receive data since 5 seconds! Make sure the input topics are published ("$ rostopic hz my_topic") and the timestamps in their header are set.

Now in CASE2

running roscore in 1st terminal

roscore

and launching rtabmap 2nd.

roslaunch rtabmap_ros rtabmap.launch rtabmap_args:="--delete_db_on_start"

and then in 3rd terminal launching freenect

roslaunch freenect_launch freenect.launch depth_registration:=true

rtabmap window opens up and starts recording images for approximately 7-10 seconds and then stops reconding new images. Now in freenect terminal the following error occurs

[INFO] [1556639771.038578426]: Stopping device RGB and Depth stream flush.

and the output of rtabmap terminal
