2º Depois começaram a aparecer caracteres estranhos no final de qualquer página que se encontra no endereço físico /etc/zpanel, por exemplo:
..</html>
&#9674;&#9612;&#9633;&#9633;&#9633;

Agora vamos aos fatos:
No mesmo servidor rodam outros virtual hosts, mas somente os que tem apontamento físico para /etc/zpanel tem esse acréscimo no final do HTML (nem sempre são os mesmos, variam de navegador para navegador), os demais que se encontram em /var/zpanel/hostdata funcionam normalmente.
Se eu copio o conteúdo de algum item da pasta /etc/zpanel e insiro em /var/zpanel/hostdata e mudo no httpd.conf do Apache o DocumentRoot (apenas altero isso, nao altero as demais opções), funciona normalmente gerando o HTML sem esses símbolos no final do HTML.
Todos os arquivos php/html tem a instrução header de charset correta e a opção de default charset do Apache está desabilitada (sempre foi assim).

Eu já alterei http.conf, php.ini mas nada adiantou.

Como exemplo segue os links:
http://zpanel.exactiweb.com/apps/webmail/ - Pasta física /etc/zpanel/apps/webmail
http://exacti.com.br - Pasta física /var/zpanel/hostdata/exacti

Obs.: Isso ocorre independente do charset ser iso-8859-1 ou UTF-8. Para verificar melhor o ocorrido sugiro que visualize o código fonte no seu web browser).

Bom galera é isso, quem puder ajudar fico grato.

Bruno

Consegui solucionar o mistério. O problema era no mod deflate. Nessa atualização ele criou a linha AddOutputFilterByType DEFLATE application/x-httpd-php no seu arquivo de configuração (/etc/apache2/mods-available/deflate.conf).

Quando a removi, tudo voltou ao normal e o apache voltou até a ser rápido em seu tempo de resposta.

Não entendi o do porque da criação dessa linha na atualização, visto que parece se tratar de compressão de arquivos php, mas pelo que eu saiba, o php gera a saída texto/html e isso depois é passado ao Apache que, dali, o deflate entra em ação e executa a compressão, enviando assim os dados para o usuário.

Fica ai a dica.

Mas agora vem outro mistério: para que raios a linha AddOutputFilterByType DEFLATE application/x-httpd-php???
