Hi Ingeborg, perhaps you can try running BIND by hand and see why it crashes on the console?
Usually the coredump is controlled by ulimit and it needs the directory (working directory of the binary, on Linux that would be /prof/<PID>/cwd) from where you launch the binary writeable. If BIND 9 crashes again we would need several things: * a backtrace with symbols, this usually needs: * unstripped named binary or named binary with matching debug symbols file * named.conf -px output - this will anonymize any secrets from the file If this involves remote crash on a remote interface (3rd party triggered crash), please send the information to security-offi...@isc.org and you can upload larger files at https://pandora.isc.org/ If this is triggered only locally by authorized users you can optionally fill new issue https://gitlab.isc.org/isc-projects/bind9 and attach the files there. To be on the safe side, please mark the issue as confidential. We will make sure that we redact any files before we make the issue public in the future. BTW is there any chance that you and Havard share any common bits of configuration?
