Title: opnsense shutting down
Post by: sigma on December 22, 2025, 04:52:34 AM
hello all,

so, I have made a pc(9th gen 9500k, 16g, 250g spinndle hdd) my router. it was running well for a long time then it started to turn off randomly but not often. today it happened 8 times(I am currently tethered to my cell phone). I have logs turned on but not sure what to look for as the logs are a lot of lines. please someone point me in a direction to look for. I have checked the PC settings(BIOS) and did not find anything wrong. I have the fans set to increase speed with temp.

thanks in advance.

Maybe start with 'dmesg' output but I think there's a good chance this is a hardware problem.  Maybe thermal or power related, or failing memory?

thank you for the reply. I will look at the 'dmesg' output after I test the hardware items you mention. It seems to be failing quicker so, I am not even sure I can check the output before it fails. This is a small form factor PC and I do not have any spare power supply's for it so, I hope it is not the PS. I started a memory test as that was the easiest for me as of now.

on the console (direct on the monitor connected to the opnsense computer) I get an error "iflib_netmap_config txr 2 rxr 2 txd 1024 rxd 1024 rbufsz 2048", after this comes up 7 times a few minutes later a bunch of lines(not the same lines) scroll down very fast and then it reboots or shuts down.

An old post from Ad explains that particular line: https://forum.opnsense.org/index.php?topic=25825.msg124748#msg124748

Doesn't seem like that one is anything to worry about.  If your system's not staying up long enough to view the logs then that makes it difficult.  Can you attach a serial console so that you can have a copy of the output as it's crashing?

You could also try running a live Linux USB (Ubuntu or something) and see if it's stable under some load, at least to rule out hardware.
