squid apache问题

li3william

我在一台服务器上运行squid 以及apache    squid反向代理 cache_peer 指向apache  然后由apache 分发请求到后端的jboss服务器上  这样一切服务都是正常的
但因为想减少这台服务器的负荷  想把apache分离到另外一台服务器上  但当把cache_peer指向到别台的apache的时候  一开始还是正常的 网站访问没有任何问题
但过了3到5分钟以后 就不正常了   网站不能访问  下面是squid上的部分配置
# hostname set
visible_hostname cache01.xxx.com
# (Format: external IP : port)
http_port 202.154.140.12:80 vhost
# for squid 2.6
#cache_peer 10.0.10.1 parent 80 0 no-query originserver (apache在与squid同台时的cache_peer)
cache_peer 10.0.10.2 parent 80 0 no-query originserver (apache在另一台时候的设置 )

其中10.0.10.1是squid服务器的内网卡ip 也是apache监听的ip   10.0.10.2是新的apache服务器的监听端口

是不是squid 与apache 一定要装在一台机器上啊？　　分离了ａｐａｃｈｅ到另台后　前期正常 过段时间ａｐａｃｈｅ进程就会卡住或者停掉

这是新apache的error_log里的一些可疑信息   
急啊。。高手们 给点思路吧。。。。
