If this is common storage, and you are running with common storage tracking active (the default) then a VSMDATA OWNCOMM report, from an SVC Dum requesting detailed information, will show the requestor's return address. That might not do you any good "this time" if it's in private storage but perhaps could give you the means to set a SLIP trap, if the address is repeatable.
