It's working now.  Fedora 19 was *not* reading the port values per below config 

    /etc/sysconfig $ egrep -B1 '^LOCKD' nfs
    # TCP port rpc.lockd should listen on.
    # UDP port rpc.lockd should listen on.

Able to manually fix by running
    bash -x /usr/libexec/nfs-utils/scripts/nfs-lock.preconfig 
        # Sources above 'nfs' config file and then runs:
        # /sbin/sysctl -w fs.nfs.nlm_tcpport=$LOCKD_TCPPORT # and another 
sysctl for $LOCKD_UDPPORT.

This bug is not in fedora 23.

$ rpcinfo -p|grep lock
    100021    1   udp  32769  nlockmgr
    100021    3   udp  32769  nlockmgr
    100021    4   udp  32769  nlockmgr
    100021    1   tcp  32803  nlockmgr
    100021    3   tcp  32803  nlockmgr
    100021    4   tcp  32803  nlockmgr
