7.4.10 breaking site to site IPsec VPN

Well boys (and girls) A couple of my fortigates got the auto update this weekend and IPSEC VPN’s are dropping packets like crazy and constantly flapping OSPF routing. Tunnels never fully drop.

Called TAC tonight and after entirely too long watching him fumble around, he looked at the case notes and lots of people calling in this weekend for these issues. 200gs, 120gs, and 100fs all rolling back tonight.
