      Since the new version of Unbound fixes it, it's unlikely to actually be related to just that one setting (DHCP lease registration), but that is the fastest way to trigger it for some people.

      I imagine others are/were hitting it as well in different ways. So there isn't a need to keep tracking potential causes now that we know the upgrade fixes it.

        @jimp So is the plan then to push 1.13.1 to the stable repo or to try to bisect through the 1.13.1 release in order to find out which patch specifically fixes the issue and just apply that patch to the version in stable?

          We'll bring in 1.13.1, there isn't a compelling case to do all the legwork to pick in partial changes at this point. 1.13.1 is a minor patch/bug fix release and the impact is low other than the fix for this which is highly beneficial.

            @jimp Speak of the devil, looks like it's already been added to the stable repos.

            For anyone coming into this thread now, you can run the following command to pull unbound 1.13.1 from the stable/2.5.x repo (I am unsure of how to update system packages from the UI, hopefully someone can chime in there):

            pkg upgrade -f unbound
            

            (you should see that it is installing unbound-1.13.1)
            Make sure to restart unbound after this package installation.

            It is probably a good idea for those who have installed the devel package to do this as well just to ensure that your systems are not a mix of devel and stable packages.

              There isn't a good way to do that from the GUI, but you could run

              pkg upgrade -fy unbound from Diagnostics > Command Prompt. Be sure to restart the Unbound service from Status > Services after.

              From the CLI the easiest way to do both is

              pkg upgrade -fy unbound; pfSsh.php playback svc restart unbound

                @jimp : I can confirm that the new version fixes it for us.

                        Hi

                        After installing unbound-1.13.1 my unbound is still restarting from time to time.
                        My system have been unstable for a long time, but I haven't had the time to dig into it. Last week I figured out that it was the unbound which is restarting. So I updated to version 2.5. But still having issues.
                        I have "DHCP Registration", "Static DHCP" and "OpenVPN Clients" enabled in my DNS Resolver settings.
                        I will try to test further and report back
                        Kind regards
                        Jens M. Kofoed

                          hmmm - running 21.02, figured hey why not upgrade unbound. Even though not seeing this issue.. But I don't see it updating to 1.13.1

                            @jimp This (upgrade of unbound to 1.13.1) sad fully does NOT fix the issue on my system. Disabling DHCP leases fixed the restarts... but this package upgrade to 1.13.1 (and restart and re-enabling DHCP leases) brought the old behaviour back (restart of unbound about every 10 minutes in my case).

                            So actually 1.13.1 at least seems to not fully fix the problem for all systems.
                            UPDATE: but again also disabling DHCP leases again for/with 1.13.1 unbound fixes it again

                              The symptom fixed by 1.13.1 is the crash/segfault.

                              "Restarting" is not a symptom of a problem, it's a side effect of using DHCP lease integration and is normal.

                                Upgraded unbound from the sable repo as described earlier, and still getting DNS Server crashes, not automatically restarting

                                Next time it happens I'll try and grab a log to post

                                      @Gertjan your on 2.5, I'm on 21.02

                                      Take it this was only released for 2.5 and not 21.02

                                        I think the common factor here is that both @johnpoz and @LostInIgnorance are using ARM devices here which presumably uses a different stable repository with ARM-specific packages.

                                        Unfortunately I know little about this but perhaps @jimp can chime in with if/when an updated package can be expected to be available for that architecture.

                                          @salander27-0 I am using a SG-5100 (not ARM) with 21.02 and no Unbound update is visible.

                                            I'm on a sg-4860.. That is not arm either..

                                            I do have some 3100's - but they are not even on 2.4.5p1 - since covid had already hit when that came out.. And sure wasn't going to update them when nobody in the office, etc.
