I would guess that this problem is due to something in your code that is not right. I don't think you want to disable undo entirely. EOEditingContext still uses it, I think.
To reduce memory usage, I have an EOEditingContext subclass that does this:
public void saveChanges()
{
super.saveChanges();
if (undoManager() != null)
{
undoManager().removeAllActions();
}
}
Does that help in your situation at all?
