配置Tomcat集群时地址冲突异常解决
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:Errorreceivingmcastpackage.Sleeping500ms
java.lang.IllegalArgumentException:Invalidpackage,shouldstartwith:{84,82,73,66,69,83,45,66}

<Channelclassname="org.apache.catalina.tribes.group.GroupChannel">
<Membershipclassname="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">
<Membershipclassname="org.apache.catalina.tribes.membership.McastService"
address="228.0.0.5"
port="45564"
frequency="500"
dropTime="3000"/></Channel>
......
</Cluster>
