You type D M E S G followed by the ENTER key after logging in to the firewall via SSH or connected to the console and selecting "8" for a shell. All lower case letters.

Is there a way to do this from the web interface ?

This screams "hardware problem". Either memory, CPU, overheating, ... or a dying SSD/disk.

What does "dmesg" output?

What makes it obvious it's a hardware problem ? Is it the "b'Bus error'" error ?
How can I check dmesg output ?

Hi,

My firewall not long ago started throwing minor erros from time to time when I have been updating it and it usually gave me the following red message on the screen: "Danger, unexpected error, check log for details." followed by the successful update with no errors even after I refreshed the page during the update. However, this time it got worse and I'm starting to worry about my firewall and its state to the point where I'm wondering if I should just re-install it alltogether, on the surface everything works fine as I checked a few things but still what happened is seriously worrying me.

When I started the update process this time around, I got the same red error message as before: "Danger, unexpected error, check log for details." with the following action still taking place for a very long time:

[19/93] Extracting liblz4-1.10.0_2,1:.

As the update was stuck on the above action taking place and the progress dot not moving at all for a long time, I then decided to refresh the web page in the browser, which at first gave me 403 Access Forbidden followed by 404 Not Found errors when I was refreshing the web page like a mad man to check if the update killed my firewall entirely. The mentioned error codes worried me that my internal devices got exposed to the internet due to the failure, also I'm not quite sure how OPNsense handles failures when something malfunctions. Once the firewall became online as I presume it rebooted, I checked a few things and everything runs fine so I don't see any issues.

During the time when the above issues with errors took place, I managed to note down the time frame of it taking place and upon checking logs on the firewall, I got the following errors, many of which were repeated in the logs at least a few times:

Is there anything in the above errors that I should worry about ? I don't really understand why my firewall is throwing all the errors, my setup is fairly basic and vanilla with no additional applications or modifications outside of what the web interface offers.
