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?
We see you are facing issues with memory leak on your firewall. If the memory leak started post the upgrade of the firewall, then it could be due to the known issues on the firmware 7.0.5v. To confirm if the firewall is matching any of that known issue, we would recommend you to create a support ticket with our TAC team.
