I think it would be valuable to understand why the memory requirements are so large and how best to manage these types of situations in addition to increasing the heap, since it seems that in some cases this merely delays the issue. Is there any internal instrumentation on Neo memory usage that could be used to help tune/tweak the settings? If not, would it make sense to add a couple of MBeans for this type of information?
