[FUG-BR] Tentando migrar o manicomio-share pra FreeBSD - 3ª tentativa

[Marcelo Gondim]

Bom dia à todos,

HAHAHa pois é estou aqui novamente tentando fazer essa proeza, que na 
época das 2 primeiras tentativas ainda era o FreeBSD 9.x o stable. Hoje 
ele roda em cima de Debian e estou novamente com um ambiente aqui para 
tentar fazer essa bagaça rodar no FreeBSD. :)

O problema pelo visto são as milhares de requisições por segundo que é 
feito pelo tracker. Site começa à entrar e então despenca. O load quando 
inicio o apache vai à uns 400 e depois vai caindo e a única coisa que 
vejo bastante nos logs é isso:

Tentei aumentar o kern.ipc.somaxconn  mas não adiantou. Alguém tem uma 
ideia sobre isso acima? Estou catando aqui Google alguma esperança. 
Porque dia 20 mudaremos de Datacenter e se até lá não conseguir fazer 
isso funcionar, vou ter que apelar novamente para o Debian rsrsrsrsr

Hoje está instalado o mariadb 10.0 + apache 2.2 + memcached. O Freeba é 
esse aqui:
