TCPCRYPT doesn't start , tcpcryptd: unknown curve nid 716

[arunjing2]

There are two hosts
Host#1: Oracle Linux 2.6.39-400.281.1.el6uek.i686
The tcpcrypt seems to be working fine on this host. Console o/p is as follows:
[root@localhost tcpcrypt-0.5]# ./launch_tcpcryptd.sh
Initializing...
Reading random seed from /dev/urandom
^C
No timestamp provided in packet - expect low performance due to calls to gettimeofday
Removing iptables rules and quitting tcpcryptd...
==== DUMPING STATE ====
FD 10 state 2
FD 4 state 1

[root@localhost tcpcrypt-0.5]#

=============================================================================
Host#2: Oracle Linux 2.6.39-400.281.1.el6uek.i686
The tcpcrypt doesn't come up. It throws following error:

[root@localhost tcpcrypt-0.5]# ./launch_tcpcryptd.sh
Initializing...
Reading random seed from /dev/urandom

nid=415
tcpcryptd: unknown curve nid 716
nid=716==== DUMPING STATE ====

Removing iptables rules and quitting tcpcryptd...

Any clue what went wrong on the second host would be useful.
