Hi, I forgot to mention my interest in this: While I don't change the sample ratio in our application, I do rebuild the tile meshes in a similar way when the user changes the elevation data being used on the fly. This issue could explain a very rare crash in our application I have seen but have never been able to reproduce.

The stack trace looks the very similar.

What will be required is a custom container of osg::oberserver_ptr<> along the lines of osg::OberservedNodePath but written to manage it's contents in a similar way to a std::set.
