Crash and brick during update

[phill]

I was updating my "firmware" and I got some kind of fatal error that bricked OPNsense.  It told me to check the log file but the Web UI died while trying to navigate to it.  After rebooting, it could not see the password file to allow me to login.  I assume that was the same problem that prevented it from doing its routing duties.  I downloaded the latest ISO and ran the install using a configuration it looks like it recovered, somehow.  I then ran another update and it crashed again.  But this time after rebooting, all the updates appear to be completed and everything seems to me working fine.  I ran the health audit.  As far as I know, that manually checked all the installed packages.  The logs do not show anything but packages being installed and uninstalled and only goes back to when I reinstalled today.  I did not see whatever the critical error was.

I've been working with Proxmox + OPNsense for about 3 years now.  I'm really happy with them on this 10 gigabit home router + firewall + VPN client + nas I built from an old computer.  I've never had anything like this happen.  I don't know what went wrong and that has left me unsure if I properly fixed it.  Does anyone have any insight about what went wrong or things I can do to make sure everything is OK?
