        For me it is intermittent, with it rebooting 50-60% of the time.

          Edit /etc/pfSense-ddb.conf and remove or comment 'reset' from the script kdb.enter.default line.

          Then after a panic the console will remain at the db prompt:

          db:0:kdb.enter.default>  capture off
          db:0:kdb.enter.default>  textdump dump
          Textdump complete.
          db> 
          

          You can then scroll back to see the backtrace shown after db:1:pfs> bt.

          You will want to restore the reset command to the file after doing that though because otherwise it will not reboot after a panic at 3am which is probably not what you want!

            thanks steve made that change but now it has been resolved. let's see what will happen

            #update reboot happened
            the console didn't remain at the db prompt.
            I suppose it is something different

                Yes it's big! The interesting part is right at the beginning of the report. For example:

                debug.kdb.panic:panic: kdb_sysctl_panic
                cpuid = 3
                time = 1691688092
                KDB: enter: panic
                [ thread pid 30195 tid 100206 ]
                Stopped at      kdb_enter+0x32: movq    $0,0x2342e13(%rip)
                db:0:kdb.enter.default> textdump set
                textdump set
                db:0:kdb.enter.default>  capture on
                db:0:kdb.enter.default>  run pfs
                db:1:pfs> bt

                That was a crash I triggered manually. Yours will probably be similar to that shown in the bug report linked above.
                Unfortunately those pictures are all from after that part.

                    Are you not able to scroll back far enough to see the initial backtrace?

                    pfSense doesn't use the standard log conf file it uses: /var/etc/syslog.d/pfSense.conf
                    So you'd have to try that there instead. I have never tried that.

                      @stephenw10 the first picture was the highest i could go....
                      So it is not possible.
                      I will try the log

                        Hmm, still odd that it doesn't save the panic as a crash report by default. The only reasons that wouldn't happen I can think of are if there's no SWAP configured (there is) or if the drive is failing and it's inaccessible at that point.

                            Did you manage to log anything?

                            If you are hitting that IPv6 issue though you could test that by simply disabling IPv6. If it still reboots when PPPoE resets that you're not hitting that bug.

                              No i couldn't log something.
                              I trying to enable console logs.
                              But it is not working
                              .
                              I will disable ipv6 and check again.

                                Hi,
                                I faced a similar issue without understanding the root cause.
                                If i remember well, I disabled the gateway monitoring.
                                dpinger (Gateway Monitoring Daemon) was probably my problem but I don't know why.
                                Do you monitor your gateway ? If yes, you can try to disable it.
                                Regards.
                                Yann.

                                  Potentially that might avoid it if the only thing using IPv6 is the gateway monitoring at that time. it would be an interesting test.

                                    @YannTKO i enabled again ipv6, disable monitor gateway of ipv6 and again reboot.. so dpinger is not the issue

                                      @stephenw10 disabling ipv6 again reboot. i think it is something with periodic reset

                                        Previously you say it was rebooting when you manually restarted the WAN. Is that still the case with IPv6 disabled?

                                            I triggered it again with different procedure.
                                            I simply disconnected wan interface with ipv6 enabled.... system reboots.
