[strongSwan] unable to add SAD entry with SPI

[徐筱莉]

Hi,
I try to establish IPSEC connection using IKEv2 （net-net psk）, but I receive an error: unable to add SAD entry with SPI c2319240
What can causes this issue?
I have checked all Required Kernel Modules in my kernel mentioned in the answer in page：http://wiki.strongswan.org/projects/strongswan/wiki/KernelModules，but error is still exsit.
Thanks for ANY advice.
