I'm doing more or less the same.

Massive children render. Caution should be taken in that collection
maintenance no to render any obsolete or removed children.

If you do not maintain carefully children components then the chance of
having that problem is greater but I've asked you because you are the chosen
one to answer that question :) Use ST tools to diagnose things. I use self
assert: in the middle of some code to cach inconsistencies sometimes. Use
anything that could help you get near the answer. Sometimes you don't find
the answer directly but doing things that leads you to a serendipity. So go
do things that favors "serendipitation".
