Crash Report Explained

  • 0_1539301818416_pfSense Hey guys,

    My pfSense box keeps hanging and not passing traffic for about 3 mins at a time randomly. Every once in a while the server will completely shut down. I got the crash logs and system logs from a bunch of crashes and have no idea what I'm looking at. If someone could take a look and explain why I keep dropping connection that would be great. I called my ISP and they verified multiple times that I'm not dropping connection at the ONT, but that they can see the NIC of my server having 1000ms packet loss. I'm including my .zip folder with all the logs I've copied thus far.

    Thanks in advance,

    You have a hardware problem.

    Those can't come from software, drivers, or anything but the hardware itself. That line appears to be saying that CPU 2 (or core 2) experienced an uncorrectable error in its cache memory.

    Could maybe be power/heat but I'd lean toward it being the CPU itself.

  • Ahh, Thanks for the reply. I'll open it up and see what's going on and probably end up swapping the CPU. Thanks again for the input!
