Linux Camel 2.15.2/netty3:DatagramChannelImpl.send0（）中的“java.net.SocketException:无效参数”

我有一个apachecamel路由，它使用netty:udp，如果请求，可以选择将udp响应发送回udp客户端，并生成一个Kafka主题。我偶尔会遇到下面的java.net.SocketException，这会导致netty停止在配置的UDP端口上侦听。我想让我担心的是，所有套接字代码都是camel-netty，这似乎是一个严重的问题，即停止路由的相关netty-UDP侦听器，我已经通过Linux-netstat命令验证了这一点

我目前正在使用-Djava.net.preferIPv4Stack=true测试JVM执行，正如其他帖子所建议的那样， 但我担心的是无效参数SocketException只会偶尔发生，所以不能确定 设置-Djava.net.preferIPv4Stack=true真的能解决这个问题吗

我想知道升级到是否可以解决此问题？我自己没有写过套接字代码，完全是驼峰代码

我运行在一台Linux物理服务器上，使用Java 1.7和RHEL-6。非常感谢您的任何想法

以下是我的路线XML：

我使用camel-netty4udp已经有一段时间了，没有出现这样的问题。我建议您使用camel-netty4，除非您有令人信服的理由坚持使用camel-netty3
