Olha Willian, que eu saiba isto ocorre quando a soma do bandwith das
filas filho ultrapassam o bandwith da fila pai.
Acho que se vc especificar o bandwith das filas filho, colocando um
valor que somadas não ultrapassem a fila pai, deva resolver.
Por exemplo
altq on $int_if hfsc bandwidth 128Kb queue { std_in, dns_in, ssh_in,
mail_in, www_in }
queue std_in 32Kb hfsc (default realtime (15% 20000
5%) \
linkshare (20% 20000 20%) \
upperlimit (30% 20000 20%))
queue dns_in 32Kb hfsc (default realtime (15% 20000
5%) \
linkshare (20% 20000 20%) \
upperlimit (30% 20000 20%))
... e assim por diante.
