apache 网站基本每间隔4天 服务器就死机 非常准时

4核8G内存，网站IP  4000左右 5M独享宽带  数据20万 动态网站，几个月之前配置没这个好  也是死机  现在我升级配置了也死机
我刚才看了下 apache日志

4000IP按理说1G内存都可以跑起来，数据太多？程序的问题？

都是cpu  容易100% 死机
如何解决? 能看到相关死机时候日志么

CPU是动态查询，或者被CC了，推荐用Nginx然后程序能静态化就静态化，动态比较吃性能，静态基本不调用数据库也没有什么CPU消耗

好的谢谢
Nginx相比Apache性能好？稳定被？
是安装好宝塔 当时推荐我安装Apache的

今天凌晨又死机了。。。有没有什么好的办法？？？

像是被CC了吧，怎么那么高的流量进服务器？
