Traffico di rete eccessivo

[alfredopa]

Salve, hp eseguito da poco l'aggiornamento firm sul 119pro alla 3.4.2, ho notato che anche dopo aver terminato il download di alcuni file torrent tramite la downlad station la spia del traffico di rete lampeggia con una velocità impressionante, cosa che non accadeva con il firm. precedente. Decido di verificare il traffico col registro del router inserendo una regola che logga tutto il traffico, e questa è una piccolissima parte del log:

Ora mi chiedo, perchè a download terminati, il qnap va a cercare tutti questi indirizzi ip generando un traffico mostruoso??? Dimenticavo, se disabilito la download station, tutto questo traffico non viene generato.
Se qualcuno ha qualche suggerimento, ringrazio in anticipo.
