Ummm vou tentar. O problema também é que o suporte do datacenter não é tão bom, eles demoram muito e eles estão 7 horas na nossa frente. Ainda bem que não é comum ter essas paradas, só fiz dessa vez para tentar migrar para o FreeBSD e acho que acabei descobrindo um problema no Hardware. Também fiz umas mexidas de tunning. Abaixo como estão:
