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.

Assunto: Re: [CentOS-pt-br] Erros nos logs
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...
