The answer is that the large exported filesystem is a very large XFS... and at least through CentOS 6, upstream has *never* fixed an NFS bug that I find, googling, being complained about in '09: it gags on inodes > 32bit (not sure if that's signed, or unsigned, but....).
Mark, are you sure your XFS is mounted with " -o inode64" option? If not, then this whole thing maybe just in XFS itself. No need to do anything, just try to remount XFS with "-o inode64" option and see if the trouble goes. Sorry if that is what you had had from the very beginning, I seem to totally have missed this thread.

The answer was to either create, or find an unneeded directory with a < 32bit inode, rename the high-number inode, move the new directory to that name and location, move everything that was under the old high-inode dir to under the new, low-number inode dir with the correct name, and reexport; I restarted nfs for good measure, and all is right with the world (well, after I restarted autofs and nfslock on the clients).
