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.
