I have a standard camera pipeline set up with nodelets:
pointgrey_camera_driver -> image_proc (debayer/rectify)
It's running inside of a nodelet manager called bumblebee2_nodelet_manager
Sometimes, it starts fine. Sometimes, it crashes horribly. All of the log files are empty.
Sample of working stdout:
... logging to /home/administrator/.ros/log/37aadb7a-e5c6-11e7-9ea0-003018cfd00f/roslaunch-alicia-huskeys-562.log
