[2.2.3] High CPU usage when going to the IPSec status page - Lot of SAD
-
Hello,
I have the following issue: plenty of SA (7997 SAD for 34 SPD), probably because of some re-keying issue (the other end of the tunnels are pfsense but in 2.2 or 2.2.1 release).
So when I try to go to the IPSec status page, it take a looong time before the page appears. And the CPU is burning:

Thank you.
