Hi, thanks for your reply! I now noticed that this error is not just happening in our setup but also on a fresh installation on Debian. The steps I did were: 1. Setup a new Debian 11 2. `apt install -y apache2 openjdk-17-jdk-headless 389-ds-base 389-ds-base-dev vim systemd-coredump gdb` 3. Install 389-dirsrv with `dscreate from-file setup.inf` with the following `setup.inf`: ``` [general] full_machine_name = vseth-test-bullseye-01 strict_host_checking = True [slapd] instance_name = auth-testenv port = 389 root_password = <PASSWORD> secure_port = 636 self_sign_cert = False [backend-userroot] suffix = dc=testoverlay,dc=vseth,dc=ethz,dc=ch ``` 4. `sysctl -w fs.suid_dumpable=1` 5. `systemctl status dirsrv@auth-testenv.service` 6. Edit `/etc/systemd/coredump.conf` and add `LimitCORE=infinity` 7. `systemctl daemon-reload` 8. `systemctl restart dirsrv.target` 9. Trigger compacting `dsconf -D "cn=Directory Manager" ldap://127.0.0.1 -w <PASSWORD> backend config set --compactdb-interval 300` -> Results in SEGV 10. List coredumps `coredumpctl list` and export `coredumpctl -o coredump-dirsrv dump <#pid>` 11. Generate stacktrace `gdb -ex 'set confirm off' -ex 'set pagination off' -ex 'thread apply all bt full' -ex 'quit' /usr/sbin/ns-slapd coredump-dirsrv > stacktrace.`date +%s`.txt 2>&1` _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
