Opa Alexandre,
Estou desconfiado que possa estar relacionado ao tráfego com quantidade de clientes na rede, mas posso estar errado também. Alguém aqui na lista possui algum CentOS servindo como Firewall em um ambiente parecido com esse que descrevo abaixo?
O Firewall segura uma rede de +/- uns 900 clientes simultâneos usando um link de 65Mbps. Se alguém tiver um ambiente parecido e funcionando perfeitamente e puder postar agradeceria muito. Porque aí vou partir pra trocar a placa de rede para outro modelo que use outro driver.

pelo jeito pode ser:
- bug do driver da placa de rede - bug no kernel - bug no iptables
acredito ser driver !! veja se no kernel do 5.3 o que mudou (drivers) provavelmente um update em algum driver...

Pessoal volta e meia estou tendo esse problema em um servidor meu CentOS
5.4
que é o Firewall da rede onde o tráfego gira em torno dos 45Mbps diariamente. Alguém já passou por esses erros e teve alguma solução?
