[Xen-users] Bridge stops forwarding on fc8 xen 3.1

[Glen Eustace <geustace@xxxxxxxxxxxxxx>]

I have raised this issue a couple of times and had no response.  I am 
hoping that in the last few months someone else may have had the same 
scenario and have had more success in resolving the issue than I am.
I have 3 domUs running 2.6.21.7-5.fc8xen, running on a 32 bit host 
running 2.6.21-7.fc7xen (xen-3.1.2-2.fc7)
I have had a number of occerances where the bridge stops forwarding 
packets from the domUs to the physical interface of the host.  The domUs 
and domU can all communicate amongst themselves but the domUs lose their 
connectivity to the outside world.  The only fix I have found is to 
reboot the phsyical server, which is a Supermicro 5014.  The server has 
Broadcom NICs and the kernel is using the tg3 driver.
I appreciate that fc7 is getting a little old but the server is 
colocated 600 miles away and hence upgrading the OS isn't currently an 
option.
ANy clues or even a pointer to a possible bug either Xen or Kernel would 
be appreciated as it least might help me determine my options.
