      Level 2 is also very verbose.
      Was able to catch another unbound crash (signal 10, SIGBUS, bus error), see below:

                Since upgrading to 2.5 my unbound is crashing regularly. I have a watchdog on it so that helps but it has been crashing sometimes 3x per hour, sometimes 2hr can go by before crashing. It seems to crash more often when I'm not using the internet but that may just be chance.

                  At the moment this still appears to be a bug in Unbound itself: https://github.com/NLnetLabs/unbound/issues/411

                  They are still investigating the cause and have not yet committed a correction.

                    I can confirm that, for me, manually upgrading Unbound to the latest version fixed the crashing. My Unbound has not crashed since the update.

                      @aaronssh said in 2.5.0 - unbound (1.13.1) exited on signal 8 (SIGFPE floating-point exception):

                      That is the same experience for most we've seen as well, but there are still some others who experience instability. Certainly less people crashing on 1.13.1, but still a significant number.

                      Actually I have one VM that crashed exactly once on 1.13.1 which never crashed on 1.13.0 (a very lightly loaded lab VM with exactly two DHCP clients). The fact that it's so unpredictable is the main problem. There are things which may compound the problem (like DHCP lease registration) but it isn't caused by them in a consistent way.

                        Hi I just purchased an SG1100 and I'm having this problem too :( .

                        I'm running 21.02.2-RELEASE (arm64) with Unbound-1.13.1 and its crashing continuously. I have watchdog restarting it.
                        I haven't been able to find a fix on the forum.
