![nginx 和 php-fpm [调试] 11：资源暂时不可用](https://linux22.com/image/647861/nginx%20%E5%92%8C%20php-fpm%20%5B%E8%B0%83%E8%AF%95%5D%2011%EF%BC%9A%E8%B5%84%E6%BA%90%E6%9A%82%E6%97%B6%E4%B8%8D%E5%8F%AF%E7%94%A8.png)
新发展
核心 php 错误日志如下，但站点特定错误日志显示了这一点。我的 php.ini 文件中的内存是：
内存大小1024；
所以这不是 php 的内存限制。我还禁用了所有插件，所以这不是我的安全插件的内存限制。
2014/12/13 16:12:40 [错误] 28264#0: *212 FastCGI 在 stderr 中发送：“PHP 消息：PHP 致命错误：/var/www/ 中允许的内存大小 268435456 字节已用尽（试图分配 71 字节）。
我在使用 wordpress 插件运行一整批导入时遇到了麻烦。当我启用 nginx 调试时，我收到此错误。结果是我随后立即收到 404 错误，并且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。
我目前所做的：
- 这看起来像是一个 nginx 错误，并且我的 nginx 版本太旧了，所以我升级了。但没有任何变化。
- 它看起来和 php-fpm 仍然有关系。我已经升级了。没有变化。
- 我已禁用所有插件。没有变化。
服务器
- CentOS 6.0
- nginx 版本 1.0.15
- PHP-FPM v 5.3.3 (fpm-fcgi)
- 网络服务器运行 3 个流量很低的网站
- PHP-FPM 设置为 ondemmand
PHP.ini 配置：
- pm=按需
- pm.process_idle_timeout = 50s
- 下午.max_children = 20
- pm.start_servers = 1
- pm.min_spare_servers = 3
- pm.max_spare_servers = 5
- pm.max_requests = 1024
- pm.status_path = /状态
我无法发布我的日志，因此请查看比较

答案1
您的日志中显示的备用进程数显然与您的 pm.min_spare_servers 值不匹配。这可能是因为 php-fpm 设置未放在您的 php.ini 文件中，而是放在 fpm.conf 文件中。
由于缺少备用服务器，出现“资源不可用错误”也就不足为奇了。但我不知道为什么会出现 404 错误。
