FG300E restarts about every 3 minutes

Hello,

 

I put new configured FG300E HA with FortiOS 5.4.7 into production network and this FG started to reboot about every 3 minutes and few seconds.

Crashlog gives no information about source.

How to debug this case ?

 

I don't want to move to FortiOS 5.6.x because many older FortiAPs will not be supported. I'm afraid to move to FortiOS 5.4.8 because of known bug: 470399 The FG-300E/301E and FG-500E/501E reboots with kernel panic errors

 

Perhaps downgrade to FortiOS < 5.4.6 ?

 

A few days ago I've made ticket in Fortinet Support but no helpful suggestions received ...

    Have you hooked up a laptop directly to the console (RJ45 serial) port to watch the whole sequence?

     

    That should show you all output during the reboot, much of which you can miss if you're just using SSH or HTTPS to access it.

    First, you should call in the number in your country/region. You might need to be in queue some time but hopefully not long. Since you already open a TT via support web site, you don't have to get it created by the first rep before you're placed in a queue. You must have attached config and other log data so it would be shorter for the tech who you grabbed to get to the speed.

     

    But likely need to flush the boot drive and reload the image either 5.4.7 or previous version you upgraded it from via TFTP, and upload the saved config of the version. Then you can upgrade to 5.4.8.

    Hello,

     

    this kind of FG300E rebooting might be linked to the usage of WiFis provided by FortiAPs managed by the FG300E. In our case after upgrade to FortiOS 5.6.3 no more such rebooting observed. If upgrade to FortiOS 5.6.3 is not an option then you might manage your FortiAPs by a separate FortiGate (connected to the FG300E).

    Despite all the vulnerabilities/CVEs we were forced to use v5.4.4 (which is not available on the Fortinet Support page, I had to create a Support ticket to be sent the firmware image).  Reading through the FortiOS v5.4.9 release notes, it appears the 300E issues have been resolved.  Will advise if any issues arise.
