apache+tomcat 集群+session复制，报故障，请高手
环境：apache2.2.4 + tomcat6.0.20 + jdk1.6在同一台pc上配两个tomcat，端口不一，启动时会有如下两种错误：
1、2013-9-12 10:03:06 org.apache.catalina.tribes.transport.ReceiverBase bind
信息: Receiver Server Socket bound to:localhost/127.0.0.1:4000
2013-9-12 10:03:06 org.apache.catalina.tribes.membership.McastServiceImpl setupS
ocket
信息: Attempting to bind the multicast socket to /228.0.0.4:45564
2013-9-12 10:03:06 org.apache.catalina.tribes.membership.McastServiceImpl setupS
ocket

ocket
2、信息: Manager [localhost#/]: skipping state transfer. No members active in clust
er group.
tomcat中配置文件如下：
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6">

下面是我在iteye上分享的我们在用的分布式Session，你可以参考一下。
