This is almost definitely my problem as my products keep direct
references to other persistent objects all of the time.

Out of curiosity, has this always been a poor practice or is it
something that changed recently?


Not sure when started to be checked, but has never been a good practice, at 
least because the memory leak it produces (circular references).

You should not store a persistent attribute that is an acquisition wrapper 
itself. (What is that... see the corresponing chapter in the Zope 
Developers Guide).
You are developing your own Product, I presume? Perhaps, you are keeping a 
direct reference to another persistent object? You should store its id 
instead, o use a container like ObjectManager.

Without more information that's all I can guess...
