I had successfully established the same tunnel a few times, but key renegotiation caused a problem ( both ends did not renegotiate at the same time so the tunnel was frozen ), i decided to kill the tunnel and start a new one ( using ipsec auto --down tunnel & ipsec auto --up tunnel ), while i was doing so, i got the oops.
