nginx&php-fpm [debug] 11：资源暂时不可用

Nginx 前端之家
前端之家收集整理的这篇文章主要介绍了nginx&php-fpm [debug] 11：资源暂时不可用，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

新发展

核心PHP错误日志如下,但特定于站点的错误日志显示了这一点.我的PHP.ini文件中的内存是：

memory_size 1024;

所以这不是PHP的内存限制.我也禁用了我的所有插件,所以这不是我的安全插件上的内存限制.

2014年12月13日十六点12分40秒[错误] 28264#0：* 212的FastCGI在标准错误发送：“PHP消息：PHP致命错误：用尽268435456个字节允许存储器大小(试图分配71个字节)在/ var /万维网/..

我在使用运行完整批量导入的wordpress插件时遇到了麻烦.启用Nginx调试时出现此错误.结果是我之后立即得到404错误,我无法完全导入我的数据.

我很确定这是一个错误,但我找不到正确的答案来修复它.

请帮忙.

到目前为止我做了什么：

>它看起来像一个Nginx bug,我的Nginx版本很旧,所以我升级了.没变.
>它看起来仍然看起来可能与PHP-fpm有关.我升级了.没变.
>我已经禁用了所有插件.没变.

服务器

> CentOS 6.0
> Nginx v 1.0.15
> PHP-FPM v 5.3.3(fpm-fcgi)
> Webserver运行3个非常低流量的站点
> PHP-FPM设置为ondemmand

PHP.ini配置：

> pm = ondemand
> pm.process_idle_timeout = 50s
> pm.max_children = 20
> pm.start_servers = 1
> pm.min_spare_servers = 3
> pm.max_spare_servers = 5
> pm.max_requests = 1024
> pm.status_path = / status

我无法发布我的日志,所以请查看比较

最佳答案
日志中指示的备用进程数明显与pm.min_spare_servers的值不匹配.这可能是因为PHP-fpm设置没有进入你的PHP.ini文件,它们进入fpm.conf文件.

由于缺少备用服务器,因此您获得“资源不可用错误”并不令人意外.我不知道为什么你会收到404错误.
