Best practice - restarting firewall?

[Kim_SandbekkbrÃ_ten]

What seems to be best practice on when to restart fortigates? 80 series and below. 

We many customers and try to restart their fortigates when they have been up for about 100+days. 

The problem comes when they have not been restarted in about 200+days. 

Then its about 50/50 chance that it will reboot correcly or just slam to the ground and not boot. 

The last customer we did this on had an uptime of 500days, when i got there i logged into the console and the it said "starting firewall". We had to format and roll back to a backup.

I just rebooted a FWF60B that was up for 640 days. Memory improved, but that was about it. It wasn't expressing any issues. I just saw that it was not being used as I poked in and it was a slow weekend, so I just did it.

It's new for me that a FG muste be restartet when they runs for xxx days.

My last 100A runs over years and the only one i must reboot was when i updated the firmware.

All of them starts up gracefully.

Ok, the only thing is possible when a firmware was buggy.

But for me nothing else is known.

Does the Fg are in a HA-Cluster?

How do they restart the FG? (execute reboot ?)

Thanks you.

We only have standalone FG, no HA.

We are using the gui and do "restart"

I Guess they both do the same thing?

Same thing, two different ways.
