[osg-users] Reference Count too high and memory not being freed

[Julien Valentin]

Hi,
I personnally don't have big experience with osgearth but I think we can't help you with such a little description of your problem...Where do you call the provided code? In an UpdateCallback?
Perhaps the best for all would be you try to reproduce the issue in a short example to make the potential bug easier to diagnose...
Cheers
