Hi Ramy, You can use the method setTargetMaximumNumberOfPageLOD of DatabasePager to try to unload the maximum number of children possible. This methods works fine for us with a lot of PagedLOD in a quadtree hierarchy with OSG 2.8.3. However the two first level of LODs aren't unload.
Now we are trying to use a PagedLOD to load a huge file of points and we have the same issue with OSG 2.9.9 and trunk version. We get an openGL out-of-memory error because the PagedLOD don't unload the children. Maybe there is some issue with PageLOD but we are not sure if our children has more references in our code and they can't be unloaded. So we are going to make some simple examples to locate the issue. If we made some progress, we will post in the list. Cheers, Maria.
