Backup of a specific VM fails all times - please help

[atinazzi]

Hi, I cannot backup a specific VM. It is a Windows SBS based VM based of 2 disks for a total size of about 50 Gb.
I can backup any other VM (including smaller Windows based ones).
I tried different media: local disks, NFS, CIFFS, but it always fails
I have apply all latest updates... I am now on 2.2-31
Following is the log:

Your run out of LVM snapshot space. Please try to increase the snapshot size in /etc/vzdump.conf (for example set 'size: 2048')
