gbSIRTS Troubleshooting: Common Issues and Fixes

gbSIRTS Troubleshooting: Common Issues and Fixes

1. Installation fails or package not found

• Cause: Missing dependencies, incorrect package name, or corrupted installer.
• Fix:
  1. Verify exact package name and version.
  2. Install required dependencies (check gbSIRTS docs or manifest).
  3. Clear package cache and reinstall (e.g., pip/npm/apt commands as appropriate).
  4. Re-download installer from official source and verify checksum.

2. Service won’t start / crashes on startup

• Cause: Configuration errors, incompatible runtime, or missing permissions.
• Fix:
  1. Check logs for startup exceptions (system journal or gbSIRTS log files).
  2. Validate config file syntax and required fields.
  3. Ensure runtime (language/runtime version) matches gbSIRTS requirements.
  4. Run service with elevated privileges if it needs access to protected resources.
  5. Start in debug/verbose mode to capture more details.

3. Authentication or authorization failures

• Cause: Misconfigured credentials, expired tokens, or wrong user roles.
• Fix:
  1. Confirm credentials and token scopes are correct.
  2. Rotate or reissue tokens/keys if expired.
  3. Verify user/role mappings and permissions in the access control settings.
  4. Check clock drift between systems if using time-based tokens.

4. Performance degradation / high latency

• Cause: Resource contention, poor configuration, or unoptimized queries.
• Fix:
  1. Monitor CPU, memory, disk I/O, and network to identify bottlenecks.
  2. Increase resource allocation or scale horizontally.
  3. Optimize configurations (thread pools, connection limits, caching).
  4. Profile slow operations and optimize queries or refactor hot paths.
  5. Use caching layers or CDNs where appropriate.

5. Data corruption or inconsistent state

• Cause: Improper shutdowns, concurrent write issues, or storage errors.
• Fix:
  1. Restore from verified backups.
  2. Run built-in data integrity checks or repair utilities.
  3. Implement transactional writes or locking to avoid race conditions.
  4. Replace failing storage hardware and verify filesystem integrity.

6. Integration or API errors

• Cause: Breaking API changes, incorrect request formats, or network issues.
• Fix:
  1. Confirm API version and update client code to match.
  2. Validate request payloads against the API schema.
  3. Check endpoint URLs, headers (including Content-Type), and authentication.
  4. Replay failing requests using curl/postman and inspect responses.

7. Unexpected behavior after upgrade

• Cause: Deprecated features, incompatible config, or migration steps missed.
• Fix:
  1. Review release notes for breaking changes and migration instructions.
  2. Reapply or adapt configuration to new schema.
  3. Roll back to previous version if needed and plan a staged upgrade with tests.

8. Logging and monitoring gaps

• Cause: Insufficient log levels, missing metrics, or misconfigured sinks.
• Fix:
  1. Enable verbose/debug logging temporarily to capture issues.
  2. Ensure log rotation and retention are configured.
  3. Integrate with centralized monitoring (Prometheus, Grafana, ELK) and add relevant metrics and alerts.

When to escalate

• Reproducible crash with no clear fix from logs.
• Data loss or corruption.
• Security breaches or suspected compromise.

Quick triage checklist (ordered)

1. Check logs and recent changes.
2. Confirm system resource health.
3. Validate configuration and credentials.
4. Reproduce the issue in a development environment.
5. Restore from backup or roll back upgrade if necessary.
