Hello,

I've posted before regarding this issue.
We currently evaluating drools 4.01 for our project. We've noticed that the perm gen space grows at a rapid rate and that eventually results
in a OOM. When shadow facts are disabled, the problem seems to go away (or at least not as noticeable as before).

Any ideas?
What is the effect of a shadowed object which itself contains complex objects that are also involved in a pattern (through inline eval)?
