I am using an Asus Xtion Pro Live with ROS Hydro in Ubuntu 12.04LTS. For launching I use the openni2_launch launch file, but today I am getting an error:

The launch of the camera goes fine but when I subscribe (or RVIZ subscribe to show the points (CloudPoints2) ) the camera nodelet manager dies with an exit code -11. This just happen when I subscribe to camera/depth/points or camera/depth_registered/points

[camera/cameranodeletmanager-1] process has died [pid 18899, exit code -11, cmd /opt/ros/hydro/lib/nodelet/nodelet manager _name:=cameranodeletmanager _log:=/home/robot/.ros/log/17f7b5ea-a24a-11e4-9a5f-00c2c6540a8d/camera-cameranodeletmanager-1.log].

log file: /home/robot/.ros/log/17f7b5ea-a24a-11e4-9a5f-00c2c6540a8d/camera-cameranodeletmanager-1*.log

How can I solve this ?

I already reinstall ROS Hydro and did not work.

Thanks
