XG Firewall keeps failing

Hi

SFV2C4 (SFOS 18.5.1 MR-1-Build326) every almost 3 weeks it's going down. We have several APIs which upload images etc. API calls traffic could be heavy sometime. We see a lot of traffic in one of our API which is hosted on IIS server. 

How can I check what is causing and what it can be done? when it happens, we can't access to web portal or any of the websites, apis which are hosted on IIS and traffic routed to firewall IP.

The only way to get it up and running again, restarting the firewall VM.

maybe the firewall is not strong enough?  Standard F2s v2 (2 vcpus, 4 GiB memory)

Thanks

  • You should update at least to 18.5.4

  • Thanks Philip. Is this the reason why the XG keep failing? I just checked the Firmware Tab, I see that 

    SFOS 19.0.1 MR1-Build365
    GA
    SFOS 18.5.4 MR4-Build418
    MR

    available to download. So should I download and 19.0.1 and install it directly? or 18.5.4 first, then 19.0.1 ?

    Thanks

  • Do a thorough backup before, then go to 18.5.4. Test it for a day or so.

    Then do the upgrade to V19 after another backup habs been taken.

    Like this you have the "inactive" firmware on version 18.5.4 for a quick rollback, if needed.
