Rede caindo constantemente

[leandrorodrigosantos]

Fui me certificar disso ja, reconfigurei todos os ip's.
As Maquinas estava todas para obterem ip's automáticos, então eu coloquei ip's em todas.
Fiz um outro teste que se mostrou estranho, o Servidor era ligado no switch de 8 Portas, até ai tudo bem.
Hoje liguei o server no router dlink e virou simplesmente um inferno, a o server começou a cair de 15 em 15 minutos.
Dlink com problema? Ele pode estar causando a falha do Server?

Dlink com problema? Ele pode estar causando a falha do Server?

Se eu te disser o que eu já passei com switches dlink, vc não acredita.

[leandrorodrigosantos]

o Switch Dlink é novo, to pensando que pode ser o roteador

[leandrorodrigosantos]

Então galera.
Boa Tarde.
Voltando ao problema.
A rede estava num estado meio critico, os switchs tinham por volta de 10 anos cada um, o roteador estava com problema e tinha um micro com a placa mãe danificada.
Fiz a troca de todos os equipamentos, switchs, roteadores e o micro com problema atualizei a placa mãe e melhorou porém ele ja é velho.
Bom durantes uns 3 dias, funcionou tudo perfeitamente, coloquei o micro velho na rede funcionou apenas 2 dias, depois voltou todo o problema.
Agora estou retirando o micro da rede e mandei reiniciar todos os computadores, inclusive o servidor, para ver se o problema era o micro realmente.
Agora a minha pergunta, se não resolver, alguma luz de alguém?

[leandrorodrigosantos]

Bom dia Pessoal.
Atualizei o Ubuntu 10.10 para o 12.04 como o colegas haviam me indicado, porém sem sucesso o problema continua.
Estou enviando o log do momento da queda para ver se alguém consegue me dar uma luz.

Você poderiam me ajudar a entender, está ocorrendo alguns erros e gostaria de entender se isso pode ser a causa da queda do server

[zekkerj]

Olha só, vc está recebendo uns erros estranhos, e eu não consegui descartar esses erros de estarem relacionados com problemas de hardware nesse servidor --- memória, placa mãe ou placa de rede.

[leandrorodrigosantos]

Será que pode ser placa mãe ou memória?
A Placa de rede eu troquei ela uma vez, coloquei uma tplink gigabit, mas acabou piorando o problema, acabou caindo muito mais do que o normal.

Essa maquina funcionou muito bem, durante 2 anos e meio, será que por ela estar sofrendo constantes acessos o dia todo pode ter gerado problemas nela? Como na memória ou na placa mãe?

[zekkerj]

Então... como eu disse, não dá pra descartar ser problema de hardware ainda. Minha sugestão é que você faça um diagnóstico de hardware nela.

Existe algum comando no linux que eu consiga fazer uma analise, se existe algum hardware com problema?
Ou existe algum programa que eu consiga fazer uma analise do hardware?

Não tenho de cabeça. Vamos ver o que os colegas dizem.

Eu tenho um programa que fica dando ping no servidor, ele não da perda de pacotes, ele simplesmente cai.
