Xen users - Sep 2010 - Two network card for domU, but one of them will freeze after a lone time.

Hi all,
   I have install xen 3.4.3 based on centos5.4.
   I changed a line in /etc/xen/xend-config.sxp like below:
(network-script network-bridge)   ---->    (network-script
my-network-bridge)

and #cat /etc/xen/scripts/my-network-script prints as below:
#!/bin/sh
/etc/xen/scripts/network-bridge "$@" netdev=eth0 bridge=eth0
/etc/xen/scripts/network-bridge "$@" netdev=eth1 bridge=eth1

My domU''s config file prints as below:

kernel = "/usr/lib/xen/boot/hvmloader"
builder = ''hvm''
name = "test"
memory = 3000
disk = [ ''phy:VolGroup00/myvmlv01,hda,w'',
''file:/root/os/Centos.iso,hdc:cdrom,r'' ]
vif = [ ''type=ioemu, bridge=eth0'', ''type=ioemu,
bridge=eth1'' ]
vcpus=4
on_reboot = ''restart''
on_crash = ''restart''
boot=''cd''
sdl=0
vnc=1
vnclisten="0.0.0.0"
vncdisplay=11
stdvga=0
serial=''pty''
usbdevice=''tablet''

After type xm create this config, I installed centos5.4 in the domU. Then
eth0 connect to in-house network, eth1 connect to Internet.
After several hours, I can''t ping the eth1''s Internet IP, like
the domU
disppears.
But when I ping the eth0''s internal IP, that will connect successfully,
and
after that I can ping the eth1''s IP again.

That why?  How to resolve?
Thanks a lot.


Best Wishes!
Qiang Ma
