Thank you for your prompt reply.
And you're correct, i apologize, i am actually using strongswan.
I am a bit reluctant to upgrade to the latest version as i have other tunnels up and running which are critical and cannot endure downtime. though i do have the upgrade task in my backlog.
As for juniper logs, this keeps reoccurring every time i try to initiate the tunnel :
