      Hi, my firewall server often crashes (when there's a big amount of requests), i use intel nics (SFP+), and newest snapshot of pfsence.

      I think this is the error:

      Fatal trap 12: page fault while in kernel mode
      cpuid = 7; apic id = 26
      fault virtual address    = 0x30
      fault code        = supervisor read data, page not present
      instruction pointer    = 0x20:0xffffffff808a566e
      stack pointer            = 0x28:0xfffffe0000521750
      frame pointer            = 0x28:0xfffffe00005217a0
      code segment        = base 0x0, limit 0xfffff, type 0x1b
                  = DPL 0, pres 1, long 1, def32 0, gran 1
      processor eflags    = interrupt enabled, resume, IOPL = 0
      current process        = 0 (if_io_tqg_7)
      trap number        = 12
      panic: page fault
      cpuid = 7
      time = 1655409054
      KDB: enter: panic

        We need to see the backtrace from the crash report at least. There is often useful data in the message buffer too.

        Do you mean the latest development snapshot (2.7.0)?

            You have two unusual things there; brigdes and oce(4)NICs. And it looks like they are combined.

            oce NICs are known to give trouble. There quite an extensive thread about it.

            Has this ever worked reliably? Did it start to fail when you upgraded to 2.7?

            Steve

              @stephenw10 Hm, I have interfaces created over the NICs, connected with bridge. And LACP on WAN ports (SFP+). Same problem when using 2.6.0.

                The easiest way to fix that is going to be to swap out the Emulex card for something else. We've spent tine trying to trouble shoot these before and never found a solution. For example:
