Take a look at the NIC and switch port flow control status during an outage, they may be paused due to switch load. Is there anything else on the network switches that might flood them every half hour for a two minute duration?
Unfortunately not. All of the NFS servers are on the same switch (an HP procurve) and only the one is having issues. The hang is always the same length, too. Nice try though!
