> Boa tarde, alguém já teve algum problema com o Roteador Cisco 3660
> utilizando 100% do processamento onde o processo "Virtual Exec" consome
> cerca de 80%?
>
> A própria Cisco tem um material de troubleshooting sobre "High Processor
> with Virtual Exec" porém o problema acontece em horários desconexos e dura
> aproximadamente 10 minutos, fora do horário de pico da rede.
>
> Atualmente este roteador possui 14 links seriais ponto-a-ponto (2mbps),
> OSPF, QoS para Voz e um link Intranet de 45Mbps da Telefônica cuja as
> conexões saintes são NATeadas.
>
> Eu acredito que por este equipamento ser antigo, possa existir algum BUG
> neste IOS ou mesmo este problema seria o limite de processamento mesmo :(
>
> Em condições normais de uso a média de processamento fica em 60% - 65% e
> processo Virtual Exec fica em 0.40% - 2%.

> Segue os show's.
