Hi Team,

We have 45 active IPSec connections in our machine. Frequently we observe couple of ipsec connections getting stale. We have to restart the IPsec to get the connections back and working properly.

Is there any solution or workaround for this issue? Please update, if any.

Version : libreswan-3.25-1.el6_9.x86_64.
Total IPsec connections: loaded 58, active 45
