[strongSwan] INFORMATION Exchange can't be recognized

[michalle OY]

hi, all
I met a problem related to information Exchange and need your help.
After the SA lifetime time out, my implementation send out a Information Exchange with delete
payload, but it seems that the strongswan doesn't recognize the Information Exchange. I tried to 
find the root cause from syslog, but it seems not related information. Would you please help to take
a look?
I have attached the syslog.
