nginx，php5-fpm崩溃

我有一个很大的问题。 我有nginx和php5-fpm的站点安装它的一切工作很好，但大约一次（有时两次，或在所有的一天）php5-fpm崩溃。 我不知道为什么。 我尝试了很多次来改变一些configuration，但没有起到任何作用。 这一切工作正常，我什么也没有改变，但有一天，我看到网站上的网关错误..

服务器：2GB RAM，Intel（R）Celeron（R）CPU 2.66GHz，debian

这里是php5-fpmconfiguration：

[www] #listen = 127.0.0.1:9000 listen.backlog = 128 listen = /var/run/php-fpm/php-fpm.sock ;listen.backlog = -1 ;listen.allowed_clients = 127.0.0.1 listen.owner = www-data listen.group = www-data ;listen.mode = 0666 user = www-data group = www-data pm = dynamic pm.max_requests = 400 pm.max_children = 45 pm.start_servers = 7 pm.min_spare_servers = 2 pm.max_spare_servers = 9 request_terminate_timeout = 0 request_slowlog_timeout = 45s slowlog = /var/log/php-fpm/slowlog.log catch_workers_output = yes php_admin_value[display_errors] = 'stderr' php_flag[display_errors] = On php_admin_value[memory_limit] = 50M php_admin_flag[display_startup_errors] = on rlimit_files = 1024 rlimit_core = 0 php_admin_flag[log_errors] = on php_admin_value[error_log] = /var/log/php-fpm/pool.log php_admin_value[error_reporting] = 'E_ALL & ~E_DEPRECATED' php_admin_value[display_errors] = off php_admin_flag[display_startup_errors] = on 

Nginx的cfg：

• 有可能提供可变参数到xinetd服务？
• sendmail.mc转发所有邮件的域名 – > [email protected]（MXlogging已经设置）
• 对init.d更深入的理解 – 他们可以调用什么？ 环境是什么？
• 服务器冻结，并突然加载非常高
• cryptsetup“普通模式”是否在每个扇区存储哈希密码？
