      I hope that it will be 23.09. The ndp fix certainly will be. ๐Ÿคž

        Ok, sounds hopeful but I appreciate this discovery came very late in the .09 workflow.

            Not yet. At least not as far as I know since we still have yet to replicate it locally. There are fixes for other things that could be interacting to cause this on some systems. If you're able to test a 23.09 snapshot and can repeatedly trigger this issue please do so.

              Still covered by this on redmine:

              Regression #14431

              No improvement yet on 23.09 dev and the issue is (probably) being pushed to 24.03, so another 6 months+ away.

              It's not ideal, I know. I'm looking for a non-pfSense option in the interim to cover the periods when I may not be around to resolve these crashes & reboots.

              In the meantime I've been pushing data at the Netgate team and running stuff whenever needed and trying every development load.

                  No, nothing substantive. Netgate did ask me to produce results with a modified kernel but the moving set of instructions left me in a bit of a hole with a router that should have been in production.

                  I am building-up a new server with pfSense+ so I can test with more freedom but my testing hours with a live WAN are limited. I could do with more help really.

                  It would really help if Netgate provided a complete version to test with, rather than being left to modify stuff myself in order to provide data for them. They expect quite a bit from a paying customer (although I acknowledge this would be different if they could replicate the issue on their own dev systems).

                  Anyway, I remain committed and will still invest the time needed where I can.

                    Yes, I'm sorry about that. Not being able to replicate it ourselves makes everything much more difficult. It's especially annoying here because I have essentially an identical setup to you. The only significant difference is the connection speed.

                    We are working to add a coredump implementation in the gui to make this process much easier.

                    In the mean time I'd be happy to work with you here if you're able to.

                    If you're able to I would simply reinstall with a much larger SWAP size to avoid the need for an external drive with SWAP.

                    Also one thing I didn't realise until I tested it was that changes to the pfSnse-ddb.conf file are read in a boot so the system needs to be rebooted normally to apply them before the panic is triggered.

                      Clearly I am happy to work with you Steve. ๐Ÿ‘

                      I just looked at the swap in the GUI dashboard, only to find there isn't one showing on my Supermicro system. Did I miss a step or something?

                      I don't recall setting a swap on my Netgate 6100 or on this machine. The 6100 shows a swap of 1024 MiB - never seen it used though.

                        Mmm, yes by default the Plus installer sets 1G for swap. The CE installer at one time used half the RAM size by default if there was sufficient drive space. I'm not sure why yours you have none.

                        A 6100 here dumps ~750MB from the kernel when configured to do so but that's after running only a short time. If you can trigger this quickly on the 6100 it would be worth trying since the worst case is that it just fails to hold the dump and reboots. If you're not using the 6100 you can reinstall it and add more SWAP, I would expect 2GB to be more than enough.

                          Under gpart I can see 1.0G of freebsd-swap - is the value used by pfSense?

                          [23.05.1-RELEASE][admin@Router-7.redacted.me]/root: gpart show

                          It's still a bit odd for it to be missing from the GUI though.

                          I'm happy to use either the Netgate 6100 or the Supermicro (SYS-510D-8C-FN6P) for testing; so your choice with repeatability vs flexibility.

                            @RobbieTT said in Wan periodic reset causes system reboot.:

                            I can see 1.0G of freebsd-swap - is the value used by pfSense?

                            See/etc/fstab

                            [23.05.1-RELEASE][root@pfSense.bhf.net]/root: cat /etc/fstab
                            # Device                Mountpoint      FStype  Options         Dump    Pass#
                            /dev/gpt/efiboot0               /boot/efi       msdosfs rw              0       0
                            /dev/nvd0p3             none    swap    sw       0       0
                            

                            When I got my 4100 (with pfSense 22.05 from back then ?), the swap line wasn't using "/dev/nvd0p3" but something else. The result : there was a swap partition but pfSense wasn't using it.
                            "nvd0p3" is my swap partition. I had to change that by editing /etc/fstab.
                            IFAIK : it was mentioning some disk ID, not the partition device name.

                            If your system starts to use the swap, consider removing stuff, typically, when you use pfBlockerng, use less bigger DNS files ;)

                            No "help me" PM's please. Use the forum, the community will thank you.
                            Edit : and where are the logs ??

                              I think that is my question, given the gpart above, should /etc/fstab be changed from /dev/nvd1p3 to /dev/nvd0p3?

                              My presumption is that pfSense uses the freebsd-swap shown in gpart but I am not certain or know why the install points to the wrong location.

                              I don't think I am close to needing swap due to lack of RAM though:

                               2023-10-16 at 09.17.00.png

                              This swap discussion is for kernel dumps, not day-to-day use.

                              [edit:] Changing to nvd0p3 and rebooting did indeed bring the GUI swap graph back:

                                Nice. Also interesting.

                                Ok so set the line in /etc/pSense-ddb.conf. I used:

                                script kdb.enter.default=capture on; bt; show registers; show pcpu; capture off; dump; reset
                                

                                Then reboot to apply that.

                                I then tested it by running sysctl debug.kdb.panic=1 which immediately panics the box and runs the script. At the console you see:

                                panic: kdb_sysctl_panic
                                cpuid = 3

                                After rebooting you should see the crash report in the gui with the vmcore offered to download.

                                If that's all working then delete that core and try to panic it by removing the interface again. Hopefully the core is not bigger than 1G if you can trigger it soon enough after boot.

                                  Thanks Steve - as the issue is intermittent for me I probably need more swap.

                                  Can I just boot from the USB installer and manually tweak the existing partitions using gpart delete / resize and whatever ZFS uses for regrow?

                                  (It's been a long time since I have used partition commands but probably not much has changed over a couple of decades... other than my memory...)

                                  Hmm, may be easier to get a new install USB but does it offer an option to set the swap partition size during the install (ie I don't remember one)?

                                    Yes, you can just set the size during the install:

                                      Now all I need is some WAN time to myself.

                                        I've racked-up the Supermicro and it has taken-over for pfSense duties, leaving the Netgate 6100 free for testing. What could possibly go wrong? ๐Ÿ˜‚
