lentidão na resolução de nomes
Olá Pessoal,
tenho um problema de lentidão em resolução de nomes há algum tempo e não vejo onde está o problema. A configuração do bind não tem nenhuma modificação, apenas o padrão após apt-get install bind9 e chrooted em /var/lib/named.
Abaixo segue uma amostra do problema:
