I am not quite sure, but for each entity bean two objects are always
created:
- remote EJB object
- object with your bussines logic.
I think that only second one is subject to pooling - so maybe you can be out
of memory because of large amounts of remote instances. This problem you are
facing to brings me again the question about the sense of entity beans.
