pfSense 2.5.2 keeps crashing periodically
-
@urquhaty Wait for other opinions.
However if you can do a fresh install and start config from scratch and it doesn't bomb, then we are getting somewhere
2.5.2 is quite stable, as a starting point too. -
The backtrace is the key part there:

Do you have any other crashes? Are they all similar?
If it's a hardware issue the crashes will be random.Steve
-
Every back trace that I've looked at is the same. (pf_test_state_udp()..., etc.)
-
@stephenw10 What is PID 12?
-
That's just the current process ID, it's not anything specific to the issue.
Nothing really jumps out from that boot log other than you have a load of devices enabled that don't need to be, sound card etc. I would disable all of that in the BIOS if you can.
Did this just start happening or has this hardware always crashed like this?

@stephenw10 This issue started happening on different hardware. Then I swapped everything out one by one to try and isolate what was causing the issue. Now the hardware is essentially a 'new' machine.
The only thing I can think of that changed elsewhere on my network would have been some Pi-hole configuration... I recently just re-enabled my domain controllers DNS server to handle local domain requests and maybe accidentally caused a DNS loop when I told Pi-hole to forward domain requests to the DC? Not sure if this is even relevant, but it's what I'm trying right now... kind of desperate at this point.
-
I can't imagine anything DNS related causing a kernel panic like that. Something must have changed though if it was running on that same hardware fine previously.
-
@stephenw10 I didn't think it would have either. It's been running for an hour and 20 minutes so far without a crash. I'm going to wait and see what happens with this change before I try anything else... I'll reply with an update later.
-
Well as much as I didn't think it could be the DNS, I think it might have been the problem. Going on strong for 4+ hours.
A note for anyone else looking at this:
I don't remember the exact setting in Pi-hole, but I think it was enabling 'conditional forwarding' for my top-level domain (tld). There was a new entry added in my dnsmasq conf file. I think it was a 'rev-server=' line and a 'server=//domain.tld' entry that I commented out and disabled conditional forwarding. This may not solve your problem or even be the exact cause, but If you changed DNS settings recently just make sure they are correct.
-
Hmm, I wonder what that's causing that would trigger this...
