    @AlexanderK

    Do you use IPv6?

      Good point, could be this: https://redmine.pfsense.org/issues/14431
      Though I'd expect to see a crash report, perhaps you don't have swap?

            @stephenw10 tried to reset manually the wan and i had a reset again. the console was like crazy. couldn't check what it was written.

            this is my disk space
            login-to-view

            does this mean that my swap is disabled?

              disabling ipv6 seems to fix the issue!

                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
