Cakephp警告session_start（）：php_network_getaddresses：getaddrinfo失败：名称或服务未知

Question

当我尝试加载任何页面时，它会给我一个警告：

  

session_start（）：php_network_getaddresses：getaddrinfo failed：名称或服务未知

此警告以随机方式出现。

调试日志：

代码

// For IE<=8
session_cache_limiter("must-revalidate");
session_start();

上下文

session_start - [internal], line ??
