Desculpe se isso parece divagado. Eu tenho tentado solucionar / resolver isso nas últimas 20 horas seguidas, enquanto tendo que tomar conta do servidor e reiniciar o php5-fpm toda vez que ele desce.
Eu imagino que exista um problema subjacente com um plug-in (site WordPress de alto tráfego) ou algo que esteja interrompendo esse encadeamento, possivelmente causando um bloqueio de dependência que está atrapalhando os outros encadeamentos. Minha preocupação imediata é encontrar uma maneira de fazer o emergency_restart_threshold reiniciar automaticamente o php5-fpm quando necessário. Então eu posso dormir e encontrar o problema subjacente do PHP. O problema aconteceu 21 vezes nas últimas 24 horas. Às vezes até 3,5 horas de intervalo, outras vezes apenas alguns minutos.
Eu experimentei vários valores de tempo, mas até agora nada parece acionar o sinal SIGSEGV ou SIGBUS necessário. Parece que uma vez que o problema começa, todas as solicitações do PHP são interrompidas, como se estivessem todas esperando algo, e os 150 Max Filhos acabam se enchendo de pedidos recebidos antes que os vários tempos limite os eliminem. Exceto quando este problema acontece, geralmente há apenas 2-5 crianças necessárias para satisfazer o tráfego atual.
Servidor é um Amazon EC2 c4.Xlarge (7,3 Gb de RAM, 4 vCPU) executando o Ubuntu 14.04.
Eu também tenho o New Relic instalado e os recursos parecem muito bons. Mais da metade da memória está disponível, e o uso da CPU é geralmente inferior a 50%, exceto após o travamento do PHP5-FPM.

Existem muitas entradas, mas todas elas se enquadram nas duas categorias abaixo.
Os FastCGI: comm with server "/var/www/cgi-bin/fastcgi.php5-fpm" aborted: read failed são gerados quando reinicio manualmente o php-fpm, quando forçosa fecha todas as conexões que ainda estão abertas.
Os stderr: Primary script unknown são causados por bots que tentam URLs aleatórios e causam erros 404.

Eu tenho muitos outros registros salvos, juntamente com notas detalhadas das minhas várias tentativas de alteração de configuração. Não tinha certeza do que mais poderia ser relevante. Feliz por postar qualquer outra coisa que ajudaria.
Obrigado por todas e quaisquer sugestões para encontrar uma solução. Mesmo que seja apenas uma solução temporária, posso deixar o servidor desacompanhado por tempo suficiente para dormir e recarregar.
