Colleagues of mine and I have been experiencing / reporting Gazebo crashes upon execution for quite some time now. I have no knowledge of their Gazebo versions etc. Additionally, I have been having my own problems with NVIDIA, which maybe muddies the waters (is this crash NVIDIA-related or just Gazebo’s? – and so on).
So, I would like to have a rough idea about the frequency with which Gazebo crashes with respect to your experience. For my setup, I would say that roughly 2 out of every 7 roslaunch-es I execute end up dead, with me having to re-execute.
