RedHat 7.3 doesn't play nice using nfs v3, so you have to force it to use v2.

The symptom is that the computer appears to lock up when reading/writing large numbers of files and/or large files. (Both have been reported, I have only managed to reproduce the large number of files in a kernel source tree unpack). Also the entire network appears to stop. Capturing the network traffic from the offending machine shows an amazing number of UDP/IP fragments.

The solution is to add the option

… in /etc/init.d/autofs.

RedHat claims that this has been addressed in the update kernel packages, but I'd rather not go there if it isn't absolutely necessary.

NetApp claims this is a systemic kernel problem requiring a kernel update>>
RedHat announcement claiming addressing NetApp NFS issues>>
NetApp document about NFS on Linux in general>>

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
