Estou executando o Drupal 6 com Nginx 1.5.1 e PHP-FPM (PHP 5.3.26) em um VPS de 1 GB de um único núcleo com 3 GB de espaço de troca no armazenamento SSD. Acabei de mudar de hospedagem compartilhada para este VPS não gerenciado porque meu site estava ficando pesado demais, então ainda estou aprendendo as coisas. Eu tenho tráfego moderadamente alto, eu realmente não monito de perto, mas o Google Adsense geralmente registra perto de 30 mil page views / dia. Eu normalmente tenho 50 a 80 usuários autenticados conectados e algumas centenas de usuários anônimos acessando o cache HTML estático do Boost a qualquer momento. Eu tenho um máximo de 10 processos filhos PHP-FPM configurados. Eu estou usando o gerenciador de processos PHP-FPM "ondemand".

Eu estou correndo em um erro ocasional que é realmente difícil de depurar porque é aparentemente aleatório. Das cerca de 30 mensagens intencionais dos usuários, uma delas é duplicada. Eu o configurei para que o botão de postagem seja desativado após o primeiro clique, portanto, não é o resultado de um clique duplo. Na verdade, aconteceu comigo uma vez quando eu estava postando. Os posts duplos ocorrem em poucos segundos um do outro. Examinei os arquivos de log e a postagem duplicada sempre parece corresponder a um erro POST nginx: recv() failed (104: Connection reset by peer) while reading response header from upstream . E este evento parece estar relacionado a um erro do PHP-FPM de um erro de timeout de execução do index.php e do SIGTERM subseqüente do processo de trabalho do PHP-FPM.

Aqui estão os%% de acesso e os logs de erro donginx e o log de erros do PHP-FPM:

Eles são removidos e levemente ofuscados para mostrar um erro de postagem duplicado que aconteceu hoje às 12:34 por mim com um endereço IP "1.2.3.4". O nó no qual o dupe aconteceu é 22802.

Esse problema não ocorreu quando eu estava executando o Apache / FastCGI no meu host compartilhado anterior. Também devo mencionar que estou usando o Redis para armazenamento em cache e o Zend Optimizer + opcache. Mas eu tentei desabilitar ambos os mecanismos para evitar o erro de dupes, e isso não fez diferença.

Obrigado por qualquer ajuda que você possa fornecer!

Bem, vou responder minha própria pergunta. O problema aparentemente tinha algo a ver com o valor request_terminate_timeout = 30s que eu estava usando, possivelmente combinado com o gerenciador de processo ondemand FPM. O post duplo sempre coincidia com um erro de timeout do PHP-FPM combinado com a morte de um processo filho imediatamente após. Por isso, desativei o request_terminate_timeout e ele parece ser redundante, uma vez que o arquivo php.ini já especifica um tempo limite de 30 segundos. Eu também percebi que eu realmente não preciso do gerenciador de processo ondemand porque eu sou o único usuário nesta caixa com uma carga razoavelmente estável, então eu mudei para static e configurei o pm.max_requests relativamente baixo para 100. evita vazamentos de memória.

Uma ou ambas as alterações eliminaram efetivamente as postagens de duplicatas.
