Do I understnad you correctly that you add osgViewer::Viewer-objects to 
a CompositeViewer? To my understanding osgViewer::Viewer and 
osgVIewer::CompositeViewer should not be used mixed. This will explain 
your problems, because in the d'tor of osgViewer::Viewer the 
DatabasePager is destroyed explicitely.

Why don't you use osgViewer::View for your views, then your problems 
should go away, and no more interfering between the two 
viewer-implementations should occur.

Cheers,
Stephan
