In several locations, I will create properties to hold the object references for bizobj classes I instantiate on my own.

Are you explicitly releasing your object references in your code? If you're just using the bizobjs in a local variable, this isn't needed.

eg.

LOCAL loBizObj
loBizObj = CreateObject("MyBizObj")

* As soon as loBizObj goes out of scope, the object reference
* will be released. No special code should be necessary to
* clean things up.

However, if you're saving an object reference in a object property, you need to release the reference when this object is destroyed.

Init() method (or where it's created):

This.oBizObj = CreateObject("MyBizObj")

Destroy() method:

This.oBizObj = .NULL.

That should cause the bizobj Destroy() method to fire, which in turn will call it's Cleanup() method and release any used datasessions and/or child business objects.
