FortiOS 7.4.3 incorrect interface utilization for SNMP on ipsec interfaces

[aguerriero]

fortiAfter upgrading to 7.4.3 my 1100E is doing something wrong when answering requests for ifoutoctets on ipsec interfaces.

Occassionaly Delta for out octets is way too high which shows an ipsec tunnel on a 40Gig interface at 90+ percent utilization while the physical 40Gig interface is reporting correctly.

I downgraded to 7.2.8... it is back to working like it should. Next stop...

This results in the delta for outgoing octets sometimes being too large, causing IPsec tunnel load to be reported incorrectly on 40Gig interfaces while the 40Gig physical interface is reporting correct data
