[rhelv6-list] MAYDAY ... very strange network breakdown/freeze with new servers and RH EL 6 x86_64

[Götz Reinicke - IT-Koordinator]

Good morning,

yesterday I got two identical new servers for running RH EL 6.

I did a basic installation with all defaults to the software selection,
the disk setup (LVM, ext4,...). After registration, I did an yum update.

The current kernel is 2.6.32-71.7.1.el6.x86_64.

The onboard LAN is 2 x 1 GBit/s Intel 82574L

The servers Tech spec can be seen here:

At installationtime I set the lan configuration to DHCP and changed it
later with the system-config-network tool to static IP and DNS/gateway
settings.

Now I'm faced with the problem, that the LAN connection freezes after a
couple of minutes and I cant restart the network service. And there are
a lot off errors and dropped packages/frames.

I checked/configured both interfaces in both servers (eth0 and eth1),
one at a time.

I reinstalled one server, thinking that may be something was broken
during installation. I checked the install dvd.

I attached a screenshot I grabbed from my remote KVM console to show the
ifconfig output.

Maybe it is an unsupported nic? Or known bug? or something else?

Any hint and help is very welcome! Best Regards

	*<:-) . Götz
