So i have a host node running 20 VEs.
From time to time HN just hangs, no ping, no ssh response. i have to reboot it by powercycling to bring it back to work.
Its 2.6.18-128.2.1.el5.028stab064.4PAE running centos 5.2

and as you can see from /var/log/messages from 10.49 to 11.25 (reboot time) server doesnt respond.

Where do i look? I have same thing happening from time to time with 2-3 of my servers.
