[Samba] samba profiling

[Andrea Cucciarre']

Hello,

I am trying to get some samba statistics on CentOS (standard samba that 
comes with CentOS), so I have enabled the profiling in smb.conf:

smbd profiling level = on

and the samba seems to be compiled with the profling option:

# smbd -b | grep -i profil
    HAVE_PROFILE_H
    HAVE_KRB5_GET_PROFILE
    WITH_PROFILE

However, all the stats values are zero in "smbstatus -P", as you can see 
below.
am I missing somthing?
