Question

FortiGate 800C Crashes, cannot connect in anyway (5.4)

Hello,

 

I am currently working on relocating a FG800C to a new office. We were running 5.0.11 and since this is a new location, I have sometime to test things I decided to try out 5.4.0. For the past 2 days the firewall has crashed and completely locked up. No WAN ping, no LAN ping, no serial console, no usb console. I know there has been some issues, but has anyone else had their firewall lock up like that?

 

I have completely wiped and restored the device and it did not help at all. If anything it crashed even quicker than it did before the factory reset.

 

My plan is to downgrade back to 5.2.6, but I wanted to see if this was a common thing.

 

Thanks!

    during product update for fortios 5.4.x the speaker discouraging us to load fortios 5.4.x to Fortigate C series fortigate models. IMHO fortios 5.4.x designed for new released fortigate models which is D series

    I am sadly reporting, that we have similar issue with FG800C, with 5.2.4 

     

    Firewall Freezing without any reason, logs showing nothing, if anyone has a clue would be great, before I need to push Fortinet to investigate what is going on with the device.

    I'm going to head into the office to hookup a console cable to a PC with putty running to text file.  I'm going to send the text file to a Windows compression enabled directory since I'm sure this file will get big.

     

    Then I'm going to execute this command and let it run overnight --

    diag debug enable

    diag debug reset

    diag debug flow show console enable

     

    It should be able to grab what's happening.  If it's a kernel panic it stands to reason that SNMP / logging won't help.

    as sad as it goes, I am sure that you can try debugging, but the fact is that 99% it's kernel panic. 

    there is nothing in logs. the firewalls are crashing 1 by one with small difference of time.

    it might be traffic related. but very strange behavior. 

     

    i will open a ticket with forti, will share the details as I get them.

     

    I am running 5.2.4 668 ( which should be very stable )
