[网络管理]双网卡服务器频繁出现 eth1 tx timeout

OS : REHL AS4U4

intel7520BD2 主板

eth0外网? ?eth1 内网 ，

数据压力大， eth0负责接收外网所有数据,eth1负责将 eth0 接受放入队列(MQ)的数据发给内网各个数据库服务器,

eth0 :? ?intel pro1000? ? ---? ? Intel Corporation 82541GI/PI Gigabit Ethernet Controller
eth1:? ? Marvell Technology Group Ltd. 88E8050 PCI-E ASF Gigabit Ethernet Controller
? ?（Marvell Yukon 88E8050 Gigabit Ethernet Controller）


eth1最近频繁down掉 ,交换机，网线都换过，系统重新做过

每次当掉，network restart , 关闭，开启网卡都不起作用，除非重新启动机器........
