      does this mean that my swap is disabled?

          Ok, seems like the issue I ran into at the redline link above.

          I need IPv6 so waiting on a fix is my only option.

            No that shows you do have SWAP enabled so I'd expect to see a crash report if it suffered a kernel panic. And your description sounds like a kernel panic. It spews the full process backtrace and message buffer onto the console before rebooting.

            We need to see the initial backtrace and panic string when that happens really. Since you can trigger it on demand, can you hook up a serial console to log it?
            If not you should be able to stop the auto reboot and scroll back through the buffer with the scroll-lock key at a vga/keyboard console.

                  I have IPv6 (from BT) over PPPoE which seems like it should be nearly identical to connections that are hitting this but I cannot trigger it.
                  There any special trick I'm missing?

                    Ooo, try disabling that and see if you can still trigger it.

                              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

                                  2fa5ef9f-18d3-41e2-b1f6-a0ea25badf22-image.png

                                      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

                                      db:0:kdb.enter.default>  capture on

                                      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.

                                            So it is not possible.
                                            I will try the log
