Rede caindo constantemente

Boa Noite Pessoal.
Estou com o seguinte problema:
Tinha o Ubuntu 10.10 Desktop instalado em um cliente como servidor, ele funcionava bem, de uns tempos para cá ele vem mostrando instabilidade na rede, ele é o servidor de um software, ele fica la bunitinho no canto dele, ninguem mexe, o problema é que o pessoal fica logado no sistema direto e geralmente a conexão com o sistema cai gerando erro no sistema. Ja troquei, Switch's, cabos, roteadores, placas de rede e não resolveu o problema.
Atualizei o Ubuntu 10.10 para o 12.04 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

Eu não sei se posso te ajudar mas vamos lá. 1º seu servidor e de que arquivos ou um firewal ...


2º isso me parece que seu switch esta travando verificar se tem loop na rede.

3º você está usando o networkManager para gerenciar sua conexão?

4º você está usando ubuntu desktop ou ubuntu server?


Fico no aguardo.

É um servidor de sistema, tem um sistem em delphi e um banco de dados firebird que fica nele, fica tudo quietinho, ninguem mexe em nada, as maquinas windows acessa o sistema delphi no linux via atalho.

Ja fiz a troca de todos os equipamentos de rede, switchs, roteador e reconfigurei todas as maquinas.

Sim, configurei a rede através do networkmanager do linux.

É o Ubuntu Desktop, não tenho conhecimento o suficiente no Ubuntu Server para coloca-lo la ainda.

Desde ja agradeço a ajuda.

No Aguardo
