Here's ChatGPT feedback regarding your server logs... Analyzing the provided log messages from a RHEL 9 Linux server, we can identify several events. Here's a breakdown of each event, including its probable cause and some examples:
1. ipa-dnskeysyncd LDAP Operations: - Messages from `ipa-dnskeysyncd` show LDAP operations related to DNSSEC key synchronization. - Example: `ipa-dnskeysyncd[75834]: ipaserver.dnssec.bindmgr: INFO attrs: <ldap.cidict.cidict object at 0x7f283b53f7f0>`. - Probable Cause: Routine operations of DNSSEC synchronization with IPA server. 2. DNS Notify Messages: - Messages from `named` indicate it received DNS notify messages for specific zones. - Example: `named[1463]: client @0x7fd61803ae68 10.12.112.3#49016: received notify for zone '0.0.0.0.0.0.a.0.0.8.9.2.4.0.6.2.ip6.arpa'`. - Probable Cause: Notification of changes in DNS zones, likely part of routine DNS zone updates. 3. dnssec-keyfromlabel Configuration Warnings: - Warnings from `dnssec-keyfromlabel` about missing configuration parameters. - Example: `dnssec-keyfromlabel[75984]: Configuration.cpp(96): Missing log.level in configuration. Using default value: INFO`. - Probable Cause: Default configuration being used due to missing specific configuration settings. 4. Systemd Service Messages: - `systemd` messages about `ipa-ods-exporter.service`. - Example: `systemd[1]: ipa-ods-exporter.service: Consumed 4.047s CPU time`. - Probable Cause: Normal systemd logging of service status. 5. Kernel Segmentation Fault (Core Dump): - Critical: A segmentation fault in `dnssec-keyfroml`. - Example: `kernel: dnssec-keyfroml[75991]: segfault at 18 ip 00007f7fba586284 sp 00007ffff3e834a8 error 4 in libsofthsm2.so[7f7fba4ef000+9b000]`. - Probable Cause: A crash in the `dnssec-keyfromlabel` process, possibly due to an issue with `libsofthsm2`. 6. Systemd Core Dump Processing: - Systemd handling of the core dump created by the crash. - Example: `systemd-coredump[75993]: Process 75991 (dnssec-keyfroml) of user 984 dumped core`. - Indicates that a core dump was generated for further analysis. 7. ipa-dnskeysyncd Python Traceback: - A Python traceback from `ipa-dnskeysyncd`, indicating an error in the script. - Example: `ipa-dnskeysyncd[75834]: ipapython.ipautil.CalledProcessError: Command [...] returned non-zero exit status -11`. - Probable Cause: The error seems related to the `dnssec-keyfromlabel` command failure. 8. Named TCP Receive Error: - Named server shutting down a TCP connection due to an error. - Example: `named[1463]: dispatch 0x7fd618009200: shutting down due to TCP receive error: connection reset`. - Probable Cause: Network-related issue or remote client reset the connection. ### Steps to Troubleshoot Core Dump To investigate the core dump caused by `dnssec-keyfroml`: 1. Locate the Core Dump: - Core dumps are typically stored in `/var/lib/systemd/coredump/` or `/var/crash/` on RHEL systems. - Use `coredumpctl list` to list all core dumps and find the one related to `dnssec-keyfroml`. 2. Analyze the Core Dump: - Use `coredumpctl info <PID>` or `gdb` to analyze the core dump. Replace `<PID>` with the process ID of `dnssec-keyfroml`. - This will provide stack traces and other details about the state of the program at the time of the crash. 3. Check Dependencies: - Ensure that all dependencies, especially `libsofthsm2`, are correctly installed and not corrupted. 4. Review Configuration and Logs: - Check the configuration files for `dnssec-keyfromlabel` and related services. - Review system logs for any anomalies or errors leading up to the crash. 5. Test in a Controlled Environment: - If possible, replicate the issue in a test environment to better understand the conditions leading to the creation of the core dump file.
