Hi Paul,

there is an IKEv2 IPSec connection (the device on the other side is a
Palo Alto), where one side has one (leftsubnet) and ~12 subnets
(rightsubnets) on the other side.
When expanding righsubnets, the following was logged by libreswan and
died. The current libreswan version is 4.3.
My question is, what could have caused this? maybe this is already known?


pluto[19191]: "test/0x11" #36161: negotiated connection
[10.10.10.0-10.10.10.255:0-65535 0] -> [10.20.0.0-10.20.255.255:0-65535 0]

Thank you for your help!
