      Hello. First off, thanks for looking and any input is appreciated.

      I have a custom built appliance, specs as below:

      Intel G5400
      4GB RAM
      SSD
      Intel Dual GB NIC

      All been running perfectly for around 18 months.

      What started to happen initially was that I would lose internet connectiviity and also lose access to the admin page of PfSense. Also unable to access via SSH.

      When I checked the box, I would notice the lights on the ethernet ports were on solid, not flashing.

      In this instance, restarting/powering the appliance off would get everything working again.

      Initially, I had no Display connected to the appliance so did not really know what was going on.

      I did an extensive SMART test on the SSD, this passed OK.

      I wiped the HDD and did a fresh install of the latest stable build.

      What happens now is that the device does not hang but will restart by itself and all is working.

      I then connected a display and noticed at the point of the internet not working, there would be a wall of scrolling text and then it would restart.

      I have attached the crash report if it means anything to anyone who can decipher it.

      Any help would be appreciated, thank you.

        Sounds like hardware issue, could be bad RAM.

          Ok, you appear to have numerous nearly identical crashes there that look like:

          You imported the config from the old install to the new one?

          Were you running 2.5 there? Because:

          <118>Loading configuration......
<118>
<118>*******************************************************************************
<118>* WARNING!                                                                    *

          You might want to rebuild the config or test with something very simple for a while.

            I did a MemTest and 15 errors were found in single pass.

              Have restored to defaults, will leave it "vanilla" for a while.

                  Yup, if you are seeing any errors at all in a memtest forget any other explanation!

                    Thanks guys.

                    Should have known to check the RAM.

                    Have replaced RAM and running PfSense at factory defaults.

                    Fingers crossed.

                      Well, over 24 hours, and rock solid since replacing RAM.

                      Even restored the config file from newer pfSense, not skipped a beat.

                      Thanks for the help guys.
