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.

Hi NoneEng
If memory still increases, it is better to create a Ticket. TAC will support you. If you can, pls share the ticket number through a message. We can try to support you too. At first, You can monitor through some commands :
diag sys top-mem
diag debug crash read

Thanks. I'll keep monitoring this.
Updated to v7.2.6, which seems to have resolved the issue. RAM peaked at 34% in the last 20 days.
That is a good news NoneEng!
