I am using strongswan to establish a vpn tunnel across AWS regions
configured on EC2 instances. It was working fine for 2 month but facing
issues when i resized the instances to lower config last week. The changes
are reverted back to previous config for all the region when i started
facing this issue.

Issue - vpn tunnel is going down very frequently (twice in approx an hour).
This is happening in production env. and i am clueless what is happening.

Attaching the syslog and config for both ends. Have replaced left public ip
with LPUBLIC-IP and right ip with RPUBLIC-IP.

OS : Ubuntu 14.04 LTS
Version : 5.1.2-0ubuntu2.4
