Hi Noel and Tobias, I saw my session was down and see the below message in strongswan logs saying SPI allocation had failed, after restarting Charon, the session came up. I was running as root. I believe the session was flapping if that is the reason for the below message or are there other reasons for this. how can I recover from this situation?, I am using a vici interface to bring up the tunnel, I did not get any message saying spi allocating failed via a vici error message.
[MGR] failed to allocate SPI for new IKE_SA Thanks, Naveen
