Do you have the 'bounce_notify_owner_on_removal' attribute on for the 
superior list, If you can tolerate that it should give you visibility of 
any bounce that triggers the suppression of your subordinate list's address 
on the superior list. You can get at the headers etc on the messages that 
are bouncing and maybe a hint as to what is going wrong.
