I the application i have inherited has all fetch.eager, and it keeps running out of memory, i feel this may be why

Almost certainly!
The Hibernate docs discuss the basics, and there has been a lot of discussion in this forum so its worth a search here.

I would recommend always using LAZY on all relationships.
