He notado que mi servidor web tiene cortes ocasionales de 1 a 5 minutos todos los días. Revisé el registro de errores de Apache y encontré lo siguiente:

Busqué en syslog y php5-fpm.log pero no pude encontrar ningún error.
en mi php.ini había configurado: error_log = /var/log/php_errors.log Pero este archivo no se genera, mientras log_errors está activado.
También intenté configurar error_log = syslog pero no se informan errores en el syslog con respecto a PHP.
¿Alguna idea de qué puedo hacer para resolver este problema? Estoy usando el servidor Ubuntu 15.04 x64, Apache 2.4.10, PHP-FPM 5.6
Respuesta1
Verifique si hay errores en el archivo /var/log/messages, allí podrá encontrar errores relacionados con el servidor.
Si sucede a una hora determinada todos los días, es posible que desee buscar el proceso cron que se está ejecutando en ese momento y que está causando el problema.
Debe verificar la carga del servidor en ese momento y si la carga del servidor está aumentando en ese momento, entonces debe verificar el proceso que causa la carga del servidor.

Intente configurar estas directivas en el <VirtualHost>bloque:
FcgidMaxRequestsPerProcess 1000
FcgidIOTimeout 3600
FcgidConnectTimeout 3600
FcgidIdleTimeout 3600
FcgidProcessLifeTime 3600
FcgidBusyTimeout 3600
Esté atento al uso de RAM. Si esto funciona, es posible que desees reducirlos y volver a realizar la prueba.
