Hello Richard,
That looks like the openswan side is trying to reauthenticate or rekey the IKE
SA for some reason.
The interesting thing to look at now is what openswan tries to do and what it
sends to the strongSwan side.
Please post a log of the system start to this event of both sides.
Mit freundlichen Grüßen/Kind Regards,
Noel Kuntze
