[FUG-BR] Server travando - Preciso descobrir o que é - Dicas.

Terça Junho 6 13:03:43 BRT 2006

Ola, lista. 

Gostaria de uma opnião de vcs... 

Estou tento problemas com meu servidor, ele fica "travando" e parece ser
problemas de hardware. Gostaria de alguma ferramenta ou algum meio para
verificar o que esta fazendo ele travar. 

Procurei no google algumas ferramentas para monitorar: temperatura da
cpu, temperatura do gabinete, discos... 

Mas gostaria de saber a opniao de vcs...

O server já está até com os discos meio sujo... de tanto reiniciar...
ehehe.

O carga dos serviços que rodam nele não é muito alta. O load fica na
media de load averages: 0.54, 0.77, 0.72

Tb rodo o apache2 nele... com uma media de 22 requisiçoes por segundo. 

Segue o status do apache:

Não parece que ele esta sobrecarregado... mas ele esta travando com uma
frequencia de 1 dia... ( to perdido !)

Acredito ser algum problema com o hardware... mas nao sei o que...

Se alguem usa alguma coisa, manda ai pra mim os links. E algumas
idéias... 

Segue abaixo o dmesg do server com problemas:
