Weird UTM freezes randomly approximately once a day ...

I have experienced a strange lockup on my "new" UTM box, but I checked log files and they don't reveal anything, just a bunch of weird characters ...

2023:03:16-01:32:01 escape75 /usr/sbin/cron[25494]: (root) CMD (  nice -n19 /usr/local/bin/gen_inline_reporting_data.plx)

So,- I've been running the software version of UTM (9.714) on my old unit (an XG115 r2) for a couple of years without any issues,
and recently I have migrated my saved config over to a new unit (XG115 r3) and a few hours after setting up the new unit (at night)

it froze up, and interfaces were not pingable (LAN) so I powered it down and rebooted. It's working again ...

Just wondering if there's something more I can look at to see what the issue was .. I have a hunch maybe it was DHCP related,
as my devices on the LAN were renewing the IP addresses and they were not in the table on the new unit, but it's a wild guess,
so if this doesn't happen again then maybe it's nothing to worry about.

I don't know if there would be an issue moving the config file (and license) from the old unit, but I wouldn't think so.

The new unit was installed the same way as the old unit, using the ssi-9.714-4.1.iso file and removing the /etc/asg with a software license,
and the old unit hasn't experienced any weird issues in years, and the ethernet ports and devices are setup in an identical way, nothing changed.

Just looking for thoughts and ideas ...

  • Hello there!

    Good day and thanks for reaching out to Sophos Community and hope you are well. 

    Wanted to check if this freeze happens often at night? or just a single occurence? 

    If ths happens often I may recommend you to open a support ticket to have this further checked, if just a single occurence we may want to observe and see if this would persist in the future. 

    Have a nice day ahead and thank you for choosing Sophos

  • I have just had another freeze but during the day, again logs show no strange information that I could find ...

    This was not happening with XG115 r2, and only with XG115 r3, and they are running the exact same configuration.
    The unit wasn't very active at the moment it happened, in fact there was no major downloads/uploads.

    It again did not respond to a single push of the power button to initiate a power down, I had to hold the button in.

    I'm wondering if it's somehow related to using configuration from the r2 unit.

    I have in the meantime run disk check via smartctl and it passed, badblocks did not find any issues as well.
    I have also performed a postgresql rebuild just in case,- after doing all that the unit still locked up ...

    Thank you!

  • I could re-install using the asg-9.714-4.1.iso instead of ssi-9.714-4.1.iso and removing the asg file,
    but I'm guessing the installation would be identical at least as far as this problem is concerned ...

    I have also just updated to 9.715-3 ...

    Next step would be to re-create my configuration from scratch and run on a more basic config to see if that helps,
    unless there's some further debugging that could be achieved by tech support personnel Slight smile

  • I'd run a disk and memory diag on the hardware before reinstalling again.

  • I have temporarily installed SFOS HW Firmware 19.x SF300, and run both disk and memory checks from sfloader.
    Both tests showed no errors so I think we can rule out any hardware related issues.

    I have now loaded the software version of UTM (asg instead of ssi) and running on my previous config to see what happens ...

  • Unfortunately the reload using asg-9.714-4.1.iso instead of ssi-9.714-4.1.iso did not solve the freezing, I used the 64 bit kernel.

    I have performed a disk check and memory check and it passes without any error.
    When the unit is frozen, you can't ping the LAN interfaces, and USB keyboard doesn't respond in order to login.
    The freezing seems to happen randomly, it looks like it happens every day ...

    I am including all fail, error, invalid messages from boot log, I do not know if these are useful at all:

  • Are you able to install some kind of windows or linux OS to the device?  Maybe run something like prime95 or equiv to load it up.  Could be cooling issues (or lack there of) causes instability.

  • I don't know, it's a regular XG115 R3 from Sophos ...

    I would expect that there would be some kind of troubleshooting path, as this appears caused by my config possibly ...

    I wonder if I could load SFOS HW Firmware and get a trial license and would be able to tell within a few days if it freezes ...

  • Why would you need a trial license?  Just install it and let it run without importing your config.  I would start from scratch and see how that works, if it's still freezing.  If it's not after a few days, it might be something in the config.  If it freezes, it's probably hardware related.
