Após uma reinicialização limpa do servidor, o servidor ficará bem. Ao visitar o site e clicar em alguns links, os processos do apache2 são criados, mas nunca terminados, e constantemente ocupam mais e mais memória até o servidor travar. A única maneira de corrigir isso é reiniciando o serviço apache2 para finalizar todos os processos ou reiniciando o servidor novamente.
Minhas tentativas incluíram a restauração do tema padrão do WordPress, a desativação de todos os plugins e a navegação no site novamente, embora pareça que o problema persista após o fato. Eu também tentei fazer pequenas configurações no apache.conf, bem como no arquivo php.ini.
Estou bastante perdida no momento e tenho feito pesquisas para tentar descobrir qual é a questão, mas só acabei em becos sem saída.
A minha pergunta é: por que o apache2 e o mysqld estão ocupando tanta memória e impedem que eles façam isso para impedir que o servidor travasse?
Abaixo está uma imagem dos processos atualmente em execução, mostrando o apache consumindo memória e gerando vários processos do apache2.
