NFS Crash crashes all hosts

[Trevor Francis]

We performed an IOZONE test through one of our VMs to benchmark our NFS store. It saturated the link, causing the NFS server to stop responding. (according to the logs on the hosts) This caused every one of our hosts (Running XS 6.02) to reboot itself.  Nov 25 09:13:24 compute0 heartbeat: Problem with /var/run/sr-mount/6b407ac5-aca7-1ade-de4e-765a728d6f52/hb-365a44b3-8083-4b3e-a748-498f3f9b0017 Nov 25 09:13:24 compute0 kernel: nfs: server 172.16.0.5 not responding, timed out Nov 25 09:15:56 compute0 syslogd 1.4.1: restart. We are running standard NFS on a linux server. The server reported no errors.  We are running CS4. Why would this happen?
