Question

我一直在使用apache cassandra 3.0.11

Datastax驱动程序：3.1.3
Netty版本：4.1.6.Final

我们在数据库方面经常出现以下错误：

INFO  [SharedPool-Worker-2] 2017-09-11 01:39:31,738 Message.java:615 - Unexpected exception during request; channel = [id: 0x22d0c179, L:/xx.xx.xx.xx:9042 ! R:/yy.yy.yy.yy:57774]

        at io.netty.channel.unix.FileDescriptor.readAddress(...)(Unknown Source) ~[netty-all-4.0.44.Final.jar:4.0.44.Final]

        at io.netty.channel.unix.FileDescriptor.readAddress(...)(Unknown Source) ~[netty-all-4.0.44.Final.jar:4.0.44.Final]

从应用程序方面我们得到以下错误：

非常感谢任何形式的帮助。
