linux系统日志报错kernel,Linux日志出现大量kernel:NET:Registeredprotocolfamily36

一台Linux服务器的系统错误日志出现大量的“kernel: NET: Registered protocol family 36”错误信息&＃xff0c;如下所示&＃xff1a;

Jul  2 05:27:45 xxxxxx kernel: NET: Registered protocol family 36Jul  2 05:27:45 xxxxxx kernel: NET: Unregistered protocol family 36Jul  2 05:28:29 xxxxxx kernel: NET: Registered protocol family 36Jul  2 05:28:29 xxxxxx kernel: NET: Unregistered protocol family 36Jul  2 05:29:10 xxxxxx kernel: NET: Registered protocol family 36Jul  2 05:29:10 xxxxxx kernel: NET: Unregistered protocol family 36Jul  2 05:30:02 xxxxxx kernel: NET: Registered protocol family 36Jul  2 05:30:02 xxxxxx kernel: NET: Unregistered protocol family 36

搜索了一下&＃xff0c;. 与 . 这两篇文章都反馈&＃xff0c;由于Linux运行在VMWare虚拟化环境下&＃xff0c;安装了vmware-tools&＃xff0c;将vmware-tools从10.0.5.-1 升级到10.1.0 就会解决这个问题。摘抄部分内容如下

Situation

Following a round of patching, it was observed that syslog was flooded with the following messages :

Resolution

The servers were running in a VMWare virtualized environment, and installed with the vmware-tools package from VMWare.

Updating the vmware-tools from version 10.0.5-1, to vmware-tools version 10.1.0 resolved the problem.

其实我们系统的错误日志跟这个基本类似&＃xff0c;除了Registered protocol family不同 &＃xff0c;那些链接里面是Registered protocol family是38 &＃xff0c;而我们错误日志中Registered protocol family为 36&＃xff0c;检查这个协议发现为XTP协议。

# vmware-toolbox-cmd -v

10.0.0.50046 (build-3000743)

# cat /etc/protocols

官方文档&＃xff0c;也有更全面的介绍。结合相关资料判断&＃xff0c;这个的确应该是vmware-tools版本引起的。
