Jeff,
Thanks for the info! How do I turn off CGLIB?

Every time the CGLIB Enhancer generates a new class, that generated class
jumps straight to the PermGen (permanent generation) of your java heap.
CGLIB Enhancers are faster in terms of performance, but more dangerous in
terms of memory consumption. (I ran into this same problem with another
product that uses CGLIB.)
Try turning off CGLIB and just have hibernate use reflection. If that
solves the problem, then you can always work on tuning CGLIB later.
