Hi, first of all, you are running outdated version of BIND 9. You can either ask Ubuntu to update to the latest 9.18.33 version or use ISC official packages
Secondly, it’s very hard to debug anything without debug symbols. You need to have a backtrace (and ideally a coredump) with debug packages installed, see here: https://documentation.ubuntu.com/server/reference/debugging/debug-symbol-packages/ Ondrej -- Ondřej Surý — ISC (He/Him) My working hours and your working hours may be different. Please do not feel obligated to reply outside your normal working hours. > On 1. 2. 2025, at 12:22, Paul Ssekamatte via bind-users > <bind-users@lists.isc.org> wrote: > > Hi, > I’m running BIND 9.18.30-0ubuntu0.22.04.2-Ubuntu in production on a > university network. > Recently, we have been experiencing the error shown below: > > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(isc_assertion_failed+0x10) > [0x7fe1b4e1d7c0] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(isc_assertion_failed+0x10) > [0x7fe1b4e1d7c0] > named[4787]: > /lib/x86_64-linux-gnu/libdns-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x3a2f5) > [0x7fe1b4c0c2f5] > named[4787]: > /lib/x86_64-linux-gnu/libdns-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x3a2f5) > [0x7fe1b4c0c2f5] > named[4787]: > /lib/x86_64-linux-gnu/libdns-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(dns_cache_create+0x1e4) > [0x7fe1b4c0cdc4] > named[4787]: > /lib/x86_64-linux-gnu/libdns-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(dns_cache_create+0x1e4) > [0x7fe1b4c0cdc4] > named[4787]: /usr/sbin/named(+0x33524) [0x562bd4cd3524] > named[4787]: /usr/sbin/named(+0x33524) [0x562bd4cd3524] > named[4787]: /usr/sbin/named(+0x41e6f) [0x562bd4ce1e6f] > named[4787]: /usr/sbin/named(+0x41e6f) [0x562bd4ce1e6f] > named[4787]: /usr/sbin/named(+0x43771) [0x562bd4ce3771] > named[4787]: /usr/sbin/named(+0x43771) [0x562bd4ce3771] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(isc_task_run+0x2bf) > [0x7fe1b4e4553f] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(isc_task_run+0x2bf) > [0x7fe1b4e4553f] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x1e993) > [0x7fe1b4e09993] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x1e993) > [0x7fe1b4e09993] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x26368) > [0x7fe1b4e11368] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x26368) > [0x7fe1b4e11368] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x26b77) > [0x7fe1b4e11b77] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x26b77) > [0x7fe1b4e11b77] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x26d96) > [0x7fe1b4e11d96] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x26d96) > [0x7fe1b4e11d96] > named[4787]: /lib/x86_64-linux-gnu/libuv.so.1(+0x91ad) [0x7fe1b468e1ad] > named[4787]: /lib/x86_64-linux-gnu/libuv.so.1(+0x91ad) [0x7fe1b468e1ad] > named[4787]: /lib/x86_64-linux-gnu/libuv.so.1(+0x250fe) [0x7fe1b46aa0fe] > named[4787]: /lib/x86_64-linux-gnu/libuv.so.1(+0x250fe) [0x7fe1b46aa0fe] > named[4787]: /lib/x86_64-linux-gnu/libuv.so.1(uv_run+0x678) [0x7fe1b4693c48] > named[4787]: /lib/x86_64-linux-gnu/libuv.so.1(uv_run+0x678) [0x7fe1b4693c48] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x2720a) > [0x7fe1b4e1220a] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(+0x2720a) > [0x7fe1b4e1220a] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(isc__trampoline_run+0x1a) > [0x7fe1b4e4d50a] > named[4787]: > /lib/x86_64-linux-gnu/libisc-9.18.30-0ubuntu0.22.04.2-Ubuntu.so(isc__trampoline_run+0x1a) > [0x7fe1b4e4d50a] > named[4787]: /lib/x86_64-linux-gnu/libc.so.6(+0x94ac3) [0x7fe1b42b3ac3] > named[4787]: /lib/x86_64-linux-gnu/libc.so.6(+0x94ac3) [0x7fe1b42b3ac3] > named[4787]: /lib/x86_64-linux-gnu/libc.so.6(+0x126850) [0x7fe1b4345850] > named[4787]: /lib/x86_64-linux-gnu/libc.so.6(+0x126850) [0x7fe1b4345850] > named[4787]: exiting (due to assertion failure) > named[4787]: exiting (due to assertion failure) > > Please advise, I have checked online with no luck. > Thanks > > with kind regards, > > Paul Ssekamatte > Directorate for ICT Services (DICTS) > Makerere University > Mob: 0782-094368 > > -- > Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from > this list > > ISC funds the development of this software with paid support subscriptions. > Contact us at https://www.isc.org/contact/ for more information. > > > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users
