4k resolution trouble

[parvu]

When exiting from roslaunch snap_cam hires.lauch , with camera_resolution value 4k system hangs:

screen output:
...
snap_cam_highres_publisher (snap_cam/snap_cam_publisher_node)

ROS_MASTER_URI=http://192.168.1.217:11311

core service [/rosout] found

and after that camera can't be accessed until reboot:

screen output:
