7484497 is the ID of the exchange where the formula evaluation failed. When you open the SQL editor (Window > Developer tools > SQL) and execute the following query:
select p.ref_id, p.name from tbl_processes p inner join tbl_exchanges e on p.id = e.f_owner where e.id = 7484497
you will get the reference ID and name of the process where this exchange occurs. You can then search for the process via this ID or name in the search box. When you open the process you should get an error message with more details.
... we will make this more user friendly in future versions.
