Symptom & Impact

Critical service remains inactive because restart burst exceeded systemd limits.

Environment & Reproduction

Occurs when ExecStart fails repeatedly during boot or dependency startup.

Root Cause Analysis

Underlying process exits quickly, triggering Restart policy until StartLimit is reached.

Quick Triage

Collect recent logs and inspect unit override values.

Step-by-Step Diagnosis

Run executable manually and validate required environment/resources.

Solution – Primary Fix

Fix root error, reset failure counter, and restart service cleanly.

Solution – Alternative Approaches

Adjust Restart and StartLimit settings if workload startup needs longer warmup.

Verification & Acceptance Criteria

Service stays active through reboot without start-limit-hit events.

Rollback Plan

Remove override drop-in and reload daemon if tuning causes side effects.

Prevention & Hardening

Add health checks and dependency ordering to avoid crash loops.

Related Errors & Cross-Refs

Related entries include Main process exited and Failed with result exit-code.
