我正在使用 Linux 系统运行一些使用 OpenFaaS 的无服务器功能。我已将所需的调用命令放在 shell 脚本中，并使用会话不断运行该 shell 脚本tmux。
我发现我的系统突然重新启动。（我尝试在使用监视器的 GUI 时检查系统。系统突然冻结然后重新启动。）此外，我正在通过连接使用我的系统ssh。我发现ssh连接非常不稳定。我发现这些问题发生在我的物理机器所在位置突然发生网络故障之后。
我尝试检查内核日志以查找可能的原因。
我发现了以下信息：
IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
每分钟都在重复。我不知道这是由于 OpenFaaS 函数正在运行还是其他原因。

有人能告诉我是什么原因导致了这个问题吗？这个消息是什么意思？以及可能的故障排除方法。
答案1
这意味着实际以太网链路每分钟都在消失，然后重新建立。
这很可能是导致之前网络中断的同一个问题——通常我会说要么是你的机器的物理以太网接口坏了，要么是它连接的交换机坏了，甚至可能是连接它们的电缆坏了。但如果本地控制台一直冻结，那可能是其他原因。
内核 IPv6 模块在链接建立方面有点冗长，但这并不意味着 IPv6 模块原因它。
