      @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

                  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.

                        I thought I already responded in this thread, might have been another. It's not up yet for 21.02, just 2.5.0.

                        The Plus repos are locked down while we work on the immediate fix needed for SG-3100. It'll be updated soon.

                            That is unlikely to be the same issue as this, I'd keep that in its own thread.

                              Jim has it ever been considered to put unbound as a package in the package manager instead of only updating it with pfSense updates?

                              pfSense CE 2.8.0

                                It isn't an add-on package, so it doesn't belong there.

                                That said, we are considering ways to trigger updates on items included in the base system, but that's a longer-term goal.

                                These kinds of out-of-band updates are rare, though.

                                    Are you running pfBlockerNG-Devel 3.0.0_10?

                                    I was trying to run this this week and my pfSense kept rebooting every hour or so too. I have since removed it and am running 2.1.4 or whatever the latest is in pfSenese 2.5.0 and its not crashing...yet. :)

                                      @jimp thanks for all your help through the years!

                                      I have a few systems that show something interesting on the serial console and believe it to be the same issue. Made us think it was a hardware fault of some sort, but entering the boot loader and starting with kernel.old seems to bypass the issue.

                                      I'll try the dnsresolver update and see if it fixes the issue.

                                        My Unbound was crashing every hour or two for several days since the upgrade to pfSense 2.5. After manually updating Unbound to the latest version, I haven't had a single Unbound reboot for the last 24 hours. That fixed it!

                                          @aaronssh awesome man! May i ask what hardware you are running? CPU / Chipset would be helpful.

                                            @salander27-0 said in Unbound crashes periodically with signal 11:

                                            unbound-1.13.1

                                            Upgrade to unbound-1.13.1 fixed this issue for me. 48 hours later no more crashes. Thanks!

                                            I followed @jimp's suggested syntax.
