Value too large for defined data type

Hi,

I’m setting up mt-daapd on Gento linux box and I got “Value too large for defined data type” error when I run mt-daapd.
Its debug message is;

* Starting mt-daapd DAAP server …
Read web_root: /usr/share/mt-daapd/admin-root
Read port: 3689
Read admin_pw: PASSWORD
Read db_dir: /var/cache/mt-daapd
Read mp3_dir: /mnt/mp3
Read servername: SV_NAME
Read runas: nobody
Read playlist: /etc/mt-daapd.playlist

Read logfile: /var/log/mt-daapd.log
Checking existence of /mnt/mp3
Bad mp3 directory (/mnt/mp3): Value too large for defined data type
Error reading config file (/etc/mt-daapd.conf)

/mnt/mp3 is a directory which has 70MB, 2 MP3 files in a NAS, linkstation(Buffaro) via CIFS.
The strage has 500GB HDD.

I’ve never seen the error before on other software on my linux box.
Anyone has any idea or hints? Thak you.
