Urgente FTP Disconecta sozinho.

Eae Galera...

Seguinte configurei o Proftpd em uma rede interna e estou passando por um pequeno problema.

Ele fica conectado apenas por alguns minutos e logo em seguida desconecta.

[root@contab_server proftp]# tail -f /var/proftpd/proftpd.log
Aug 10 11:42:58 contab_server proftpd[5130] contab_server: Failed binding to 0.0.0.0, port 21: Address already in use
Aug 10 11:42:58 contab_server proftpd[5130] contab_server: Check the ServerType directive to ensure you are configured correctly.

Percebi essa mensagem no log, alguém pode me ajudar?
