Hi.
I write a procedure that remove a node and it gets an OutOfMemoryError with
-Xmx128m.

This node may be huge (By example, all data stocked from an user). In my case,
this node contains a hierarchy of 40000+ nodes.
Also note that since, my application use concurrency and I use a
TransientRepository, I have always another session that is open.
So I think it have to do with the cache/replica system that save change in
memory before session.save().
All I think is to use a recursive algorithm that save each time a node is
removed. But I would prefer to keep my data always consistent for other users.
Any idea?
