Fall in warehouse (2,4)

I think it could be either:

Which length description are you looking for?:

2,4

go down

This clue is a double definition.

'fall' is the first definition.
(going down is a kind of falling)

'warehouse' is the second definition.
(I've seen this before)

'in' acts as a link.

(Other definitions for go down that I've seen before include "Be recorded" , "Sink" , "leave university" , "Fall" , "Warehouse" .)

I've seen this clue in The Telegraph.
