Attempting to apply to recent nfs rpc.statd fix does not work with a rpm -Fhv on RedHat 6.1 systems. The nfs-utils package does not obsolete the knfsd packages -- these have to be removed by hand. (When these are removed, the process leaves nfsd and mountd running.) The install of nfs-utils does not restart nfsd and mountd, so an old copies of these daemons could still be running.
