No, it should clean up nicely.
There are two reasons for the behavior you're seeing:
1. There is a global vector to map IDs to FieldContainers, which right now
never
shrinks. Depending on the number of nodes in your file, that might make for a
fairly slow memory creep. We have not found anybody having a real problem with
this, except for showing up in artificial memory tests. ;)
2. If you turned on writing ChangeLists, those keep track of all changes and
need to be cleared if the changes are not used. Call
OSG::Thread::getCurrentChangeList()->clearAll(); in the loop and see if that
makes a difference.
Hope it helps
Dirk
