标题: CentOS 5.1 断网问题
我使用的是 CentOS 5.1 出现了断网情况。大概十几个小时一次。就连接不了，必需使用server network restart重启才能正常
下面是出现两次时的日志

我只能初步的判断是有个 restorecond服务定时执行的问题。

NETDEV WATCHDOG: eth0: transmit timed out

这个似乎是你的网卡有问题哦。

不会吧。是不是驱动有问题？

作者: yangjie_sz 时间: 2009-12-22 11:44
你的网卡是主板集成的吧， r8169
应该不会是驱动的问题，这些集成网卡的支持 CentOS 5.1 应该是很完善的了。

嗯。是网卡集成的。

作者: chenyx 时间: 2009-12-22 14:33
下载网卡驱动安装下吧

把没用的服务都关掉，使用IPv6了吗？没用的话也关掉。
再试试。

发现在很多DROPPED

没人知道嘛。

标题: 把IPV6功能屏蔽，网络没有断过，
现在我把IPV6功能屏蔽，网络没有断过，
但丢包的现象还是存在。
