Tengo un servidor web nginx + php-fpm
Entonces noté en php5-fpm.log muchas líneas extrañas:

¿Alguien puede decirme cómo son estos segundos after 321.722533 seconds from start
y qué significa?
UPD
Mi config es:
pm = dynamic
pm.max_children = 50
pm.start_servers = 20
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_requests = 100
321
segundos y se reaparecerá. No puedo prestarle atención?log_level
parámetrophp-fpm.conf
desdenotice
(ese es quizás el valor predeterminado) awarning
¿Qué dice tu
max_requests
entorno? Si este es un sitio web ocupado, es probable que esté reciclando sus procesos secundarios una vez que alcanza ese número de solicitudes, a menos que diga 0, en cuyo caso podría estar llegando a un tiempo de espera interno y cerrando procesos secundarios para ahorrar memoria durante los momentos de silencio. Sé que el procesador FastCGI para IIS hace esto; Es probable que sea la misma situación aquí.Src: http://php-fpm.org/wiki/Configuration_File
EDITAR: Entonces eso es lo que está sucediendo. Tan pronto como un niño llega a 100 solicitudes, se cierra. PHP-FPM abrirá uno nuevo cuando sea necesario (que podría ser inmediatamente).
