Hello libreswan community,
I am experiencing some SA retransmission issues for my IKEv2 connection. The
connection had been stable and worked pretty well until recently.
From the pluto logs it seems the IPSec tunnel was successfully established but
at the same time the pluto daemon is re-transmitting the SA response to the
client / initiator due to receiving a duplicate SA init request. Below is the
log paste for the connection:

That looks like a bug on oue end but:
Libreswan version: 4.3
Linux Distro: Debian 11
Cloud Premise/Fabric: AWS EC2 (t4g.nano on arm64, us-west-2)
Please try 4.7 or 4.8 to see if the issue goes away? The liveness code
has seen some changes since 4.3.
