Apache代理tomcat总不时出现循环重定向，如何解决？

Apache代理tomcat能够跑起来,但是浏览器访问的时候,不时出现循环重定向的提示, 刷新几下又好了,日志方面也看不出什么原因,还望大神指教
我贴一下我的配置 服务器是win2003 64位, Apache 2.2, tomcat 7
Apache
1, 通过http模式, 加载这两个模块

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

2,配置了下线程数

KeepAlive on
KeepAliveTimeout 15 
<IfModule mpm_winnt.c>
ThreadsPerChild 500     
MaxRequestsPerChild  5000     
#Win32DisableAcceptEx
</IfModule> 

3, 配置vhost Include conf/extra/httpd-vhosts.conf
vhost.conf 配置

    <VirtualHost *:80>
    #ServerAdmin webmaster@dummy-host.example.com
    DocumentRoot "c:/Apache2/docs/"
    ServerName test.abc.com
    ServerAlias test.abc.com
    ErrorLog "logs/test.abc.com-error.log"
    CustomLog "logs/test.abc.com-access.log" common
    ProxyPreserveHost On
    ProxyPass /arrow-test/rescources !
    ProxyPass  /arrow-test http://127.0.0.1:8080/arrow-test
    ProxyPassReverse  /arrow-test http://127.0.0.1:8080/arrow-test
    ProxyPass /resources !
    ProxyPass  / http://127.0.0.1:8080/
    ProxyPassReverse  / http://127.0.0.1:8080/
</VirtualHost>

tomcat 下面两个项目一个arrow-test是后台,一个arrow-test-front
配置的路径分别是 /arrow-test 和 / , resource是资源文件夹
