Troubleshooting CoreFloo-D: Common Causes and Fixes

Troubleshooting CoreFloo-D: Common Causes and Fixes

1. Symptom: Service fails to start

• Likely cause: Configuration file syntax errors.
• Fix: Validate config with the bundled validator or run corefloo-d –validate /etc/corefloo-d/config.yml. Correct YAML/JSON syntax errors and restart.

2. Symptom: Repeated crashes / segfaults

• Likely cause: Incompatible plugin or corrupted build.
• Fix: Start in safe mode: corefloo-d –safe-mode to disable plugins. If stable, re-enable plugins one at a time to find the culprit. Reinstall from a verified build if crashes persist.

3. Symptom: High memory or CPU usage

• Likely cause: Memory leak or misconfigured cache limits.
• Fix: Check process memory with top/htop. Review application logs for leak traces. Adjust cache and worker settings in config (e.g., reduce worker_count, lower cache_size). Apply latest patch addressing leaks.

4. Symptom: Authentication failures

• Likely cause: Expired credentials or misconfigured auth provider.
• Fix: Verify token/certificate validity. Test auth provider connectivity. Reload credentials and confirm time sync (NTP) on server; reissue tokens if expired.

5. Symptom: Slow response times

• Likely cause: Network latency, DB slow queries, or thread pool exhaustion.
• Fix: Run traceroutes and measure RTT. Profile DB queries and add indexes or optimize queries. Increase thread pool or connection pool sizes; enable request sampling to find hotspots.

6. Symptom: Data inconsistency between nodes

• Likely cause: Replication lag or split-brain during network partition.
• Fix: Inspect replication lag metrics. Re-sync replicas using the provided resync tool: corefloo-d resync –target-replica . Resolve split-brain by promoting the correct primary and reconciling divergent data using last-writer-wins policy or manual merge.

7. Symptom: Configuration changes not applying

• Likely cause: Changes not reloaded or config file path mismatch.
• Fix: Confirm active config path with corefloo-d –show-config-path. Apply changes and reload service: systemctl reload corefloo-d or use hot-reload endpoint if available.

8. Symptom: TLS/SSL handshake errors

• Likely cause: Unsupported cipher, expired certificate, or hostname mismatch.
• Fix: Check cert validity and chain with openssl s_client -connect host:port. Ensure SNI and hostnames match. Update cipher suites and certificate chain.

9. Symptom: Log flooding / disk usage high

• Likely cause: Verbose logging level or lack of log rotation.
• Fix: Reduce log level in config, enable log rotation (logrotate or built-in), and compress/rotate old logs. Clear large temp logs safely.

10. Symptom: Upstream integration failures (API/webhooks)

• Likely cause: Schema mismatch, rate limits, or network blocks.
• Fix: Verify payload schema and headers. Check upstream rate limits and backoff logic. Ensure firewall allows outbound connections; inspect HTTP status codes for clues.

Diagnostic checklist (quick)

1. Check service status: systemctl status corefloo-d
2. Inspect logs: journalctl -u corefloo-d -n 200 or tail -F /var/log/corefloo-d/*.log
3. Validate config: corefloo-d –validate
4. Check resources: top, df -h, free -m
5. Test network: curl -v, ping, traceroute
6. Verify auth/time: check tokens and timedatectl status
