Serveur vsftpd ne prends pas les gros fichiers

Q) Help! I'm getting the error "426 Failure writing network stream." on
downloads.
A) You shouldn't see this with v1.2.1 or newer versions of vsftpd. Older
versions of vsftpd can give this error if the user tries to download
something from an unusual filesystem (e.g. FAT), which don't support
performance features used by vsftpd. With vsftpd-1.1.3 and newer there is a
config workaround, use_sendfile=NO.

Est-ce qu'il reste de l'espace disque sur le serveur ? 

Est-ce que tu as testé avec un autre fichier ? 

Quel est le système de fichier utilisé par le serveur ?
