一台高负载的虚拟空间服务器，因为客户数量大请求大，所以可能会导致同时出现的503错误多，最新的litespeed自动开启了 auto fix 503 error ，导致在错误出现较多时自动重启litespeed，造成客户无法访问
选项解释：
Auto Fix 503 Error
Specifies whether to try to fix the “503 Service Unavailable” error by restarting the server gracefully. A “503” error is usually caused by malfunctioning external applications and a web server restart can often fix the error temporarily. If enabled, the server will restart automatically whenever there are more than 30 “503” errors within a 30 seconds span. This feature is enabled by default.Syntax: Select from radio box
为了提升最大兼容性，关闭即可。
