[求助]用LVS with ldirectord 做的web load balacne 经常出现apache 自动关闭:(

Submitted by leon3020 on 周日, 2006-07-02 06:16

之前用的时候也是会出现其中一个real server的apahce自动退出，现在随着访问量增大，ldirectord一启动没多久就会出现这样的问题，，，现在我单开一个realserver没问题，，说明问题是出现在ldirectord 上面，，请问各位有什么好的处理方法么？

环境：一台vs并兼作ls，一台rs。

各位请帮忙。。

可能要查一下在apache和ldirectord将要退出前系统的状态，例如内存的使用状况。是不是内存快要用尽了？

文松博士，我用的是wrr调度算法，这里提到http://www-128.ibm.com/developerworks/cn/linux/cluster/linux_cluster/part3/index.html：但是当负载变化很频繁时，它会导致负载失衡，而且那些长请求会发到同一个服务器上。是不是因为这个原因？但是也不会导致apache自动退出阿。。。请文松博士帮忙！！！非常感谢先！！！
