Estou com um problema no meu servidor CentOs 6.6, estão aparecendo vários processos e ele está usando muita memória. Em um dia estavam normais, com o uso da memoria abaixo de 1Gb, no outro dia começou a aparecer vários processos e o uso da memória foi lá para cima, usando os 3,8GB, mesmo com o site tendo poucos acessos simultâneos.
