Hello,
After a very chaotic upgrade (https://forum.opnsense.org/index.php?topic=52060.msg272561) on my HomeLab firewall, I took extra care with my HomeProd, and the process went entirely differently. No packages were removed, the DHCP server was not cut over, etc. I had to do all that manually, even though I'd done the pre-work to make it a smooth transition.
I've had a few times now, over the past few weeks, two events that seem unrelated but both keep occurring. One, is the firewall itself crashing. This is annoying, but not a huge issue since it automatically reboots. A couple weeks ago (I think - I didn't write down exactly when), it had one of these crashes, only it didn't bring up the Kea DHCP server when it restarted. I've had it on my list to investigate more, and then this morning, there was no crash (uptime of 9 days, so perhaps that's when the previous crash was), but Kea was stopped again. In both cases that Kea has been stopped, clicking the "Play" button on the "Services --> Kea DHCP --> Kea DHCPv4" page is all I've had to do to resolve the issue.
As I was getting ready to make this post, I decided to check for updates, and in the process of applying them, the firewall crashed again. Kea came up properly from the crash, but it's concerning I have two different critical components (the kernel and Kea) that can't seem to stay running.
Every time I have a crash, I submit the logs using the webUI reporter page, but never get any feedback whatsoever on it.
Attaching the Kea logs where the service stopped. Also attaching a screenshot of the latest kernel panic.(May take a 2nd post because apparently I've hit a space limit.)
Was on 26.7.2 prior to this morning's updates; now on 26.7.3.
Kernel panic screenshot from this morning, immediately prior to submitting via the Reporter.
