In the destructor of the node/nodes perhaps Thats where I would place a break point

As the topic is related: Do you know where I have to set a breakpoint to see if an object like a node really gets deleted? I want to free some memory. Therefore I remove the node (and some other stuff) from the scene-graph like this: if (TheNode.get() ){ osg::Node::ParentList parents = TheNode->getParents(); for(osg::Node::ParentList::iterator pitr=parents.begin(); pitr!=parents.end(); ++pitr) { (*pitr)->removeChild(TheNode.get()); } } And then remove the reference like this: TheNode= NULL; So if I really got all references removed, it should delete the node, right? I have the impression that the node doesn´t get deleted (I created some hundred nodes for testing and removed them this way, memory-consumption didn´t go down), so either my approach is wrong, or I forgot some reference somewhere.
