我的临时解决方案是重新启动 mysql 服务器服务...现在可以使用...
谁能告诉我是否可能触发此问题或者我该如何解决此问题？
P.S 我也尝试在 my.cnf 中增加 -> 从 max_allowed_packet=16M 到 max_allowed_packet=128M...我以为它修复了它，但它又回来了
最佳答案
打开 wp-includes.搜索 wp-db.php 文件。如果找到该文件，请使用文本编辑器将其打开。使用文本编辑器的搜索工具搜索:
$this->ready = true;
找到该行后，在找到的行后面添加以下行:
//WP Query Gone Away Error Fix
$this->query("set session wait_timeout=600");
保存文件。现在，当您检查网站的错误日志时，您将不再看到错误，这意味着网站不会像以前一样宕机。
这只是一个临时修复。您不能 100% 确定错误不会再出现。通过执行此“修复”，MySQL 将等待一段时间来完成查询。以下是一些永久修复此错误的提示:
尝试禁用/删除需要大量内存的插件 一一禁用插件，找到导致这个错误的插件 使用您只需要的插件。更多的插件意味着更多的CPU内存和MySQL服务器将过载
