SSL VPN Maxing out CPU Usage on VDOM

Hello,

 

I'm encountering an issue with a Fortigate. When I enable an SSL VPN Policy, using the SSL VPN as the source interface and many destination interfaces with destination IPs, the CPU usage jumps to 97% instantly. When I disable that policy, it goes back to about 0% usage. This is happening on a Fortigate with 2 VDOMs, and only one of them has an active SSL VPN policy in. The Firewall is set to replace another aging firewall, so it's not fully in production yet, but it's very concerning to have SSL VPN shoot the CPU usage to maximum.  Fortigate 200F, in HA mode, Version 6.4.6.

"diag sys top" then shift-p before enabling the policies to see what processes are using up the CPU time most.

Then open a ticket with TAC to get analyzed.
