Eu tenho um servidor dedicado com o apache2. recentemente o apache começou a morrer quando o site não está sendo usado.
exemplo ontem 08:00 eu estava fazendo alguma programação no site tudo funcionou bem.
hoje, 10 da manhã, quando eu tentei logar, ele me deu a mensagem "server something.com was to slow to load"
agora, uma vez que eu uso o serviço apache2 restart ele funciona bem novamente! Eu sou muito novo para isso, alguém pode me dizer o que procurar?
também tentei verificar a versão do apache2 instalada e em vez disso recebi a seguinte mensagem:

qual é a sua versão do Ubuntu?
Se for 14.04-16.04, verifique:
sudo gedit /etc/apache2/sites-available/000-default.conf
se você mostrar apenas = /var/www
então alterou para = /var/www/html
E reinicie o apache
sudo service apache2 restart
