配置Tomcat集群时地址冲突异常解决

FXMAR

　　TOMCAT集群配置好后运行正常，首次访问该服务后出现以下错误：
警告:  Error receiving mcast package. Sleeping 500ms
java.lang.IllegalArgumentException: Invalid package, should start with:{84, 82, 73, 66, 69, 83, 45, 66}

tomcat集群教程的默认配置address="228.0.0.4"修改为address="228.0.0.5"

 <Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Membership className="org.apache.catalina.tribes.membership.McastService"
                        address="228.0.0.5"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
出现此问题的原因可能是局域网中存在其他集群机器组

　　具体位置在server.xml文件中：
　　<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
　　<Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Membership className="org.apache.catalina.tribes.membership.McastService"
                        address="228.0.0.5"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
　　</Channel>
　　......
　　</Cluster>
