Approx. every 12 Hours the Sophos restarts

Marc Finger

Hello everyone,

I have a strange problem with my Sophos XG. It freezes approx every 12 hours and needs a hard reboot. 

 

All services stopp, Internet is not working anymore and the webinterface is offline. As soon as I do a hard reboot, the firewall is up and running for (at the moment) approx. 12 hours. The strange thing is the reboot intervall changes, so sometimes the firewall is running for weeks without any problems and sometimes it needs a restart a couple of times per day. At the moment we are in the 12 hours time frame. Strange thing is, the reboot occurs nearly at the exact same time of the day.

 

Is anyone experiencing simillar problems? I thougt that it was due to TCP Flood attacks but I setup the DOS protection settings but the freeze still happens. 

 

Thank you very much for your help. 

Best regards,

Marc

    Hi Marc

    please tell us about your hardware, the environment it is located in?

    Hi Ian,

    thank you for your quick reply.

     

    It is used at home with 30-40 devices of devices connected but most of them without internet connection (smart Home). 

     

    I use 2 ports just WAN and LAN, nothing bridged directly on the device. 

     

    Otherwise it is a J1900 30GB SSD 4GB RAM with 4 intel NIC. 

     

    Strange thing, as soon as I upgrade another Firmware the reboot time  changes. With one firmware I havent had any problems at all, but after an upgrade the problems started again.

    Hi Marc,

    I would suggest it is your SSD being too small. I will get criticised again over the disk size, but I think you need a minimum of 60gb for home use.

    I find your 30-40 devices that do not require access to the internet rather odd for a smart home. All my smart devices require internet access which I have restricted.

    The SSD is around 50% use. I disabled a lot of not needed logs. And I dont understand why the system is working again for some time if the SSD is full. There is also no log entry regarding the reboot, it just stops working but you have no sign (slower internet connection) beforehand. After the reboot everything is working perfectly for some time unless it crashes again. 

     

    The smarthome devices are connected to my own server, and are not allowed to connect to the internet at all.

    The amount of disk usage is not really relevant because the main partition or swap apportion could fill. What you are describing is a classic case of disk either being full (specific parts) or failing.

    Okay. Perfect thank you.

    I will get a bigger one and get back to you if it solved the problem. :)

    Hi,

    I have had similar issues since i upgraded to latest version, i did mention it on one of the threads when i had to hard reset.  I went back to SG UTM 9 for now as i had to reset mine daily between 8-12 hours.

    The device i use is a Qotom Mini PC i7 with 4 Intel LAN ports, 8GB RAM and 250GB SSD.

    Thanks

    Try to run a memtest first. Had this on a SG120 where I had 2 devices with same setup and one of them was freezing every couple of days(both on 64gb SSD drives). And it was the one with the least of rules. If you have an SSD 64gb lying around you can try it also but first check the memory! These little buggers can cause all sorts of problems if they're missbehaving!

    Thank you will also try the RAM.

    It is really annoying, will let you know the result.

    Hey,

    Quick update:

    I did a check of the SSD and RAM via the Sophos tool. SSD no error. The RAM test stopped but without any error.

    I changed the RAM Modul and no fail since 3 days.

    Thank you for your help.

    I will update this thread in case of another fail.

    Best regards
