You need to look at the output of `setkey -D`, `setkey -DP`, `netstat -sp e=
sp`,
`tcpdump -ni` on the network interface and check what actually is going on.
Provided information is not enough for debugging. As I said this looks more
like a problem with racoon, duplicate SAs, SPs or something like this. For
example, in log you have two SAs with different SPI for the same direction.
Before starting racoon, make sure that you have cleaned up from previous ru=
n on
both sides.
