Files not cleaning up with admin script

[Yosu Tamayo]

Hello everybody,

I am having problems cleaning up deleted rooms. I have created a public 
restricted  room and  uploaded some docs, then I have deleted the room.
Before deleting the room I got this from the admin command.
 ./admin.sh -f
Setting default logging context: default
Temporary upload files allocates: 0
Upload allocates: 8,2 MB
Recordings allocates: 31,7 MB
... Done


After deleting the room

./admin.sh -f cleanup
Setting default logging context: default
Temporary upload files allocates: 0
Upload allocates: 8,2 MB
Recordings allocates: 31,7 MB
... Done



 ./admin.sh -f
Setting default logging context: default
Temporary upload files allocates: 0
Upload allocates: 8,2 MB
Recordings allocates: 31,7 MB
... Done

Am I  using the correct syntax? Is there anything more to do for 
deleting unusable uploads?

Thanks,
