And, now it has crashed. So whatever the issue is, the kernel-2.6.18-308.1.1.el5 does not fix it. As suggested on the RHEL5 list, I have shifted the problem VMs off of the virtio disk driver and to the standard driver. you do this as detailed in this mail: https://www.redhat.com/archives/rhelv5-list/2012-March/msg00017.html We will see if this fixes the issue.
