请教Centos5.6网络故障的问题。。。

勤奋学习linux

跑的是CentOs5.6+lamp,  最近几日随机会出现网络不通，ping的时候提示超时，重启计算机后就恢复正常，但隔开几个小时或一天又出现同样问题。

在故障发生时我曾尝试server network restart， 结果没啥用。 故障时，用top命令查看cpu、内存占用也不高。




另：/var/log/message的日志：

......// 都是重复的日志，此时ping提示已经超时了。。。

楼主去Intel官网看看有没有设备的驱动.还有,chkconfig xinetd stop;service xinetd stop
先关闭xinetd服务,观察下

经过观察，有新的线索， 当出现ping不通时，我把httpd重启一下，就能ping通了。

看来和httpd有关系，下一步应该如何检测，请大侠们指点。
