  First, what version are you using ? CVS ?
  Second what function() generate that node set, where do the node
comes from ? The function is responsible to provide the persistency 
of that set of node.

  Which function creates nodes ?
The problem is the lifetime of the nodes. It's a VERY HARD problem indeed.
Without precise examples it won't get anywhere. If your code creates
node to return them into node set, it better provide persistency for those.
