Hi all,

Has anyone seen this before? I'm running a CentOS 5.3 with xen 3.0 and the server has been running fine for a long time. In fact, it was up for 186 days before I had to reboot after the "network died", and I couldn't fix it.

The server has multiple domU's on it, which all still works when the host node (dom0)'s network dies with these errors.

I have to run /etc/init.d/network restart for it to work again. How can I permanently fix the problem?
