I did some tests, it is the line include "/var/lib/samba/bind-dns/named.conf"; which trigger the coredump. this file contains only a call to database "dlopen /usr/lib64/samba/bind9/dlz_bind9_18.so -d 9"; This file exists rasp:/var/lib/samba/bind-dns # ls -l /usr/lib64/samba/bind9/dlz_bind9_18.so -rwxr-xr-x 1 root root 67632 Feb 23 20:13 /usr/lib64/samba/bind9/dlz_bind9_18.so Regards Created attachment 875282 [details]

output of command coredumpctl dump pid -o output.core
This core dump is still present. I have set the debug level to 9 in the command "dlopen /usr/lib64/samba/bind9/dlz_bind9_18.so -d 9" and restarted named. Here the output of command coredumpctl dump.
hello, tjere is a message on the samba mailing list refering to the same problem in debian and a answer about this see https://lists.samba.org/archive/samba/2024-June/249319.html " We had bind segfaulting before already. It was a bug in samba, - samba used a symbol name dns_domain_equal(), which is an obvious name of a function but it's obvious for both named and samba internal dns, and so both named and samba had it, the prob was when the two tried to load into the same address space (where symbol names are unique), so a wrong symbol were used by one of the components. We renamed this function in samba to fix the issue. " Can you have a look? in the samba mailing list there is a proposed solution: "Seemingly you need to set an environmental variable LDB_MODULES_DISABLE_DEEPBIND The easiest way I found to do this was to create a systemd override file systemctl edit named.service Add (where it tells you to): [Service] Environment="LDB_MODULES_DISABLE_DEEPBIND=1" Save and close the file. Now start Bind9" I tested this on tmy pi 400 system and it wotks. Maybe this line can be added in the existing /usr/lib/systemd/system/named.service.d/26-samba-dlz.conf Regards Philippe Condé I've added the samba maintainers since it seems more like a samba issue. Could you maybe take a look? As far as I understand he report in samba bugzilla it seems that bind-9.18.27-1.1 use per default jemalloc, but the library /usr/lib64/samba/bind9/dlz_bind9_18.so from package samba-ad-dc-libs use malloc from (glibc?). Theses functions can't work together.the current work around but not a real solution . I think that the package samba-ad-dc-libs must be enhanced with a new function for bind >= 9.18.27 regards Philippe I see that there was a fix released for Factory/samba, thanks Samuel. @Philippe can you confirm and possibly close the issue?
