RabbitMQ 3.13 restart loop on Arch Linux — initialization taking 468s, systemd timeout exceeded, service killed by watchdog, crash loop back-off, port 5672 connection refused
Neural Engine Root Cause Analysis
Process crash loop detected — a service is repeatedly crashing and restarting, failing to reach a stable running state. This indicates a persistent issue such as a missing dependency, corrupted configuration, incompatible library version, memory corruption, or an unhandled exception that occurs during startup. In Kubernetes environments, this manifests as CrashLoopBackOff with exponentially increasing restart delays.
Remediation Plan
1. Check service logs immediately before each crash for the error message or stack trace.
2. Look for core dumps in /var/crash/ or the configured core dump location.
3. Verify all dependencies (config files, environment variables, database connectivity) are available.
4. Roll back to the last known working version if the crash started after a deployment.
5. For segfaults, check for library version mismatches or corrupted binaries — reinstall the package.
