Write-error no swap-device, Resultado: hostbyte = DID_BAD_TARGET driverbyte = DRIVER_OK

Question

Meu servidor raiz em 1 & 1 não respondia em HTTP e SSH, então eu entrei no console serial. Ele inundou minha conexão com mensagens de erro intermináveis como citadas abaixo.

Eu iniciei uma reinicialização e agora tudo parece funcionar corretamente.

Depois do google, eu instalei o smartctl e fiz um curto auto-teste, que me disse que o dispositivo era saudável.

É provável que ocorra uma falha no disco ou pode ser apenas um programa que está ficando louco? Eu suponho, o dispositivo de swap também pode crescer quando grandes quantidades de memória são consumidas por um programa com bugs? Como posso saber com certeza?

O servidor já não respondia há uma semana quando eu o reiniciei sem uma investigação adequada.

O servidor está rodando no CentOS.

Eu estava com medo disso. Esse é um problema conhecido com esse modelo de unidade específico. Use outra unidade. p>
