Symptom & Impact

A custom or packaged service on Ubuntu 22.04 fails immediately and systemd reports start request repeated too quickly. Application remains offline and dependent services fail transitively.

Environment & Reproduction

Host runs systemd 249 on Ubuntu 22.04 LTS. Reproduce with invalid ExecStart path, missing environment file, or permission errors that trigger repeated crash and restart cycles.

Root Cause Analysis

systemd throttles services that crash repeatedly within StartLimitIntervalSec. Root cause is usually application startup failure, bad unit directives, or unresolved dependency ordering.

Quick Triage

Check unit status and recent logs, then validate executable path and file permissions. Avoid disabling restart policy before identifying the first actual failure event.

Step-by-Step Diagnosis

Review unit file syntax, inspect override drop-ins, and run systemd-analyze verify to catch directive errors. Reproduce binary startup manually using the service user account.

Solution – Primary Fix

Correct ExecStart and environment references, reload daemon, reset failure counter, and start service again. Confirm WantedBy and dependency directives align with runtime requirements.

Solution – Alternative Approaches

Use an EnvironmentFile to separate variables, add ExecStartPre health checks, or replace brittle shell wrappers with direct binary invocation in unit definitions.

Verification & Acceptance Criteria

Service stays active for at least 10 minutes, restart counter remains stable, and dependent units start without timeout or dependency-chain failures.

Rollback Plan

Revert unit file to previous version, daemon-reload, and restart. If issue persists, disable auto-start and run app manually while collecting debug logs.

Prevention & Hardening

Version-control unit files, validate changes with systemd-analyze verify in CI, and use health probes to detect bad deployments before production restarts occur.

Related Errors & Cross-Refs

Frequently paired with permission denied on runtime directories, missing After=network-online.target, and stale PID files from abrupt process termination.
