eth1 goes to sleep when tired - well that was silly

Quoting Dave Stevens <geek at uniserve.com>:

> I have a little 2P server with 2 ports, eth0 and eth1. eth1 is

should have been eth0 is connected...

> connected to a router and dsl service it shares with other computers.
> It works fine. I need a faster dsl service so I have a different ISP's
> dsl modem connected to eth1. eth1 is connected to a ubuntu 10.04.1
> instance running apache2 to serve pages for a custon on-line service.
> Everything works fine for a while and whenever we are using the eth1
> service, but when we stop using it, the eth1 port somehow shuts down,
> no outside access is possible through ssh or the web. But if I tunnel
> in through the other port (eth0) and ping the outside world, or do a
> traceroute, then all of a sudden the access from outside is restored.

> The server has CentOS in dom0 and uses Xen virtualization. There is a
> web server running in another domU CentOS instance that uses eth0 and
> has no issues. The motherboard is a Supermicro dual cpu with 2x
> opteron 2376, 16G ram, raid-10 storage.

> I don't know where to look for more info. Baffled by this.

> Any ideas welcome.
