      Hi Everyone,
      This is my first build of Pfsense. Just now encountered a crash report on the dash board. Could someone help me interpret this one.Appreciate so much to those who will reply and suggest what will I gonna do with it. I'm currently experiencing high latency as well on one of my NIC maybe this is one of the reason im having having latency.

      Fatal trap 12: page fault while in kernel mode
      cpuid = 1; apic id = 01
      fault virtual address = 0x40979b
      fault code = supervisor read data, page not present

      stack pointer = 0x28:0xfffffe0000364760
      frame pointer = 0x28:0xfffffe0000364790
      code segment = base 0x0, limit 0xfffff, type 0x1b
      = DPL 0, pres 1, long 1, def32 0, gran 1

        That text does not contain enough information to determine what happened. It should have offered to let you download the crash report which would contain all of the available information.

        Also you should be using 2.4.5, not 2.4.4.

            I don't recall seeing that particular backtrace or set of errors recently (if ever). If this is a new setup then it's possible there is a hardware issue on that network card, or perhaps a bad interaction between the hardware and the OS. You might make sure that the BIOS is completely up-to-date.

                Everything in my last post. The first part is the crash backtrace. It crashed while attempting to locate a PPPoE session (which is also indicated in the second part, the end of the system message buffer).

                Looking back through the backtrace you can also see it was using "lem" which is Legacy em(4) which generally means you are using a rather old Intel network card. Nothing wrong with that per se, but depending on its age, and the age of the hardware in general, it could have a hardware issue.
