Random Reboots

[dbass81]

I seem to have random reboots.  Sometimes I will have great uptime (1-2 days), but OPNSense will randomly reboot, especially when I'm using it.  I went to System -> Log Files -> General in the WebGUI, but it only shows logs after it rebooted.  What log files should I be looking at to find the problem (I've checked /var/log, but I can't see anything).

You may have a hardware issue. To start the process of elimination, boot from a memtest86 USB stick and test your RAM: https://www.memtest86.com/download.htm

It's an older AM3 motherboard with 4 GB (2x2 GB) DDR3 RAM.  I'll try that, thanks!

I've been testing my RAM for the past 8 hours with 0 errors.  If it's not the RAM causing random reboots, is it something else?  Are there any logs which would indicate a hardware/software problem?

The kernel logs would be worth checking, but given that it runs for a while it is unlikely to be the boot process.

Vintage AMD has a problem with thermals. Can you run a stress test with s-tui and keep an eye on the temperature? https://pypi.org/project/s-tui/

I never did figure out what the cause of the reboots were.  I would hear the BIOS beep and not the OPNSense reboot beeps.  I switched back to a dual core Intel CPU and it's really stable.
