pfSense reboots during large downloads

  • I'm running 2.4.4-RELEASE-p2 (amd64) on an AMD PC with Intel NIC. Anytime that I have large throughput the system reboots. I'm not sure if it's both up/down or just down, as I don't usually upload huge stuff, but it will do it when downloading a Windows/game update/large file/etc.

    I have an OpenVPN tunnel that I'm routing [essentially] all my traffic through. I have also tried enabling/disabling hardware encryption.

    I don't see anything in the Status -> System Logs. How should I go about troubleshooting next?

    If you have a serial console, leave a client open and connected to it, either with a large scrollback buffer or logging all output. Then monitor it during a reboot, see if you get any output.

    If you only have a video console it's harder to capture errors, but you still might see something.

    If there are no crash reports and nothing in the logs, then it's harder to diagnose. That said, it's almost certainly hardware if that is the case. If it's crashing under load, which could be from the encryption required to run the VPN, then most likely it's heat or power-related, but it still could be anything (RAM, CPU, etc)
