1、问题描述
    WebLogic10gR3集群环境，日志中不断报出如下错误，但是应用系统访问正常。####<2011-9-15 下午08时58分22秒 CST> <> <> <> <1316091502360> java.io.StreamCorruptedException: invalid type code: 11

2、可能原因
    WebLogic集群内部配置多播地址和端口通信，另外应用采用了JBoss缓存+JGroup同步，也配置了相同的多播地址和端口。可能是由于集群收到了其他的UDP包不能识别造成。等待调整为不同的多播地址和端口再观察。

3、经修改缓存的多播端口为另外的端口，问题解决。
