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?
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.
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
