php - 无法分配内存错误问题

Question

我在Wordpress上收到“无法分配内存”错误，其他任何线程都没有帮助我，所以我决定再次询问我的具体情况。

我使用以下规格运行专用服务器:



在服务器上，我运行一个Wordpress成人网站，该网站允许用户流传输服务器上托管的视频。 -----> NSFW My Website

由于某种原因，我不断在下面收到此错误:

(12)Cannot allocate memory: couldn't create child process: /usr/sbin/suphp

一次将多个(10-100)个视频“发布”到网站时，才出现此错误。

以下是我的php.ini中的代码

upload_max_filesize = 3000M
post_max_size = 2000M
memory_limit = 5000M
file_uploads = On
max_execution_time = 300

当我不单击“发布”时，这就是从GoDaddy上的服务器管理器中看到的样子



另外，这是最近一次批量发布后出现的更多错误，此错误将持续约2-3分钟，然后完全停止

我没有使用CloudLinux并且未启用RLimitMEM

这是我的/wp-includes/default-constants.php

// Define memory limits.
    if ( ! defined( 'WP_MEMORY_LIMIT' ) ) {
        if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
            define( 'WP_MEMORY_LIMIT', $current_limit );
        } elseif ( is_multisite() ) {
            define( 'WP_MEMORY_LIMIT', '512M' );
        } else {
            define( 'WP_MEMORY_LIMIT', '512M' );
        }
    }

    if ( ! defined( 'WP_MAX_MEMORY_LIMIT' ) ) {
        if ( false === wp_is_ini_value_changeable( 'memory_limit' ) ) {
            define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
        } elseif ( -1 === $current_limit_int || $current_limit_int > 268435456 /* = 512M */ ) {
            define( 'WP_MAX_MEMORY_LIMIT', $current_limit );
        } else {
            define( 'WP_MAX_MEMORY_LIMIT', '512M' );
        }
    }

Answer 1

通过增加apache配置文件

中的php.ini内存限制来解决此问题

确保/usr/local/lib/php.ini中的memory_limit值设置为更高的值

提高/wp-includes/default-constants.php中定义的wordpress内存限制
