I've just tried OpenSWAN 2.6.34 on both sides of the tunnel with the same result: errno 17.

I am not sure but I think it is useless to test newer versions of either kernel or OpenSWAN in my case.
The problem is in my system. Tunnels are not disconnected before reboot or HW switch off and the main question is whether
IPsec implementaion is able to handle such a situation under conditions I've described in previous emails?
