      Yup need to see the backtrace. However that appears to be different.

      If you have a number of crash reports and they are all different it's probably a hardware issue.

          Still need to see a backtrace. And posting new threads just confuses everyone.

          How many crash reports do you have? We need to compare multiple crashes.

            Sorry for the confusion, yes it is the same system and yes and disabled darkstat. Multiple crashes occur and continues.

              Ok, can you upload any further crash reports to the Nextcloud link?

              Or just give us the backtraces here to compare?

                @patient0 I did. Still happening. I bought this Topton pfSense router from AliExpress two months ago.

                  @stephenw10 I'll post backtraces later as I am not home. Thank you

                      This line
                      current process = 7 (pf purge)
                      indicates that the error occurs at the pfSense boot stage when initializing the PF kernel module.
                      I would recommend to install the system again first

                      It is possible that there is some kind of problem at the hardware level

                        @Konstanti The last two differnet codes happened after I put an external USB fan (plugged to device the wall) under the router as per seller recommendation to dispense heat. Recorded temperature at 4 cores reach 62 Celsius though Pfsense occasionally throughs 70 Celsius.

                        Correlation vs causation? I am just trying to exclude.

                          Did the fan bring down the CPU temps? On an N100 that's normally passively cooled any fan should have a dramatic effect. If it doesn't I would check the CPU is correctly attached to the heasink/case, has thermal paste etc.

                          There are 4 distinct crashes there. One each in darkstat and netstat and all the others in pfctl and pfpurge which are very similar:

                          All of those crashes are after bootup completes.

                          Nothing else significant is shown. How long does it take to crash after booting?

                              @stephenw10 random between 1-2 days. However, when I removed the fan the system was stable for 4 days. I put the fan and connected it throught a USB on wall outlet within two days two crashes and froze once.

                              Now I removed the fan completely and I am watching. Next I'll check the thermal paste and update.

                              Any chance how clear darkstat remnants files or other packages (I already removed them)?

                                @stephenw10 Yes, the fan brought the temperature down to 40 Celsius.

                                Anything I can do to clear darkstats/ netstat remnants cache files?

                                  darkstat was the 1st crash like 20days ago (1719551956). The netstat crash was the 5th of July (1720211173).

                                  Hard to imagine the fan caused a crash. Especially if it wasn't powered from the device itself.

                                    @stephenw10 A little update since last crash July 17th, no more crashes after removing the external (or USB) fan.

                                    I am now inclined to believe that trying to cool the processor is the culprit for the crash. The processor seems to be very sensitive to temp change.

                                    Hope this will help someone else. I'll post here if anything changes.

                                    Thank you for your insight.

                                      Hmm, odd. Hard to imagine that it doesn't like running cooler! 😕
