After upgrading our Fortigate 600E (two firewalls in HA) first to FortiOS 7.0.4 then later 7.0.5 we are experiencing what I suspect is memory leak issues.
Over time the memory usage goes up gradually to the point where the firewall goes into "conserve mode" and traffic forwarding stops. After reboot (HA failover) the memory usage is back down and then after about three weeks it goes into conserve mode again.
Anyone else experiencing the same problems?
Do you think I should just roll back to 6.4.x or wait for the next patch?

The memory usage issues we experienced after upgrading from 6.4.x to 7.0.x seems to have been resolved with upgrading to 7.2.0 so I consider this case closed.
When I ran into these leak problems using v6.2.9, I had to install an auto-script to have the FGT kill processes when the conserve mode threshold was exceeded (so I could sleep at night). In this case, https processes were running wild, sometimes starting 17 at a time, with just 1 user logged on.
You can script on the FGT itself or on a FAZ.
Tonight I upgraded the 600E's to FortiOS 7.2.0
In a couple of weeks I probably know if the memory leak issues are resolved.
You mean "downgraded" from 7.2.5 to 7.2.0?

Upgraded from 7.0.5 to 7.2.0
FortiOS 7.0 expands visibility and control, ensures the consistent deployment and enforcement of security policies, and enables centralized management across the entire distributed network. For more details aslo see

The the memory leak issues are resolved with the upgrade to the 7.0.2? We have the same issue with 400E models.
I assume you mean upgrade to 7.2.0? Anyway.. it seems the upgrade has resolved the memory usage problem. I need a few more days to be absolutely sure but it seems fine now.
Is upgrading to 7.2.0 the solution?
