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 process[snap_cam_highres_publisher-1]: started with pid [3037] ^C[snap_cam_highres_publisher-1] killing on exit terminate called after throwing an instance of 'boost::exception_detail::clone_implboost::exception_detail::error_info_injector<boost::lock_error >' what(): boost: mutex lock failed in pthread_mutex_lock: Invalid argument shutting down processing monitor... ... shutting down processing monitor complete done Unhandled exception in thread started by sys.excepthook is missing lost sys.stderr screen output end

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

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

ROS_MASTER_URI=http://192.168.1.217:11311

screen output end
