# Self-Healing CI: Auto-Retrying a Transiently Timed-Out Step

> A step that times out once but completes on retry hit a transient slowdown, not a hang. See the manual fix and how self-healing CI retries it.

A step that blows its time budget once and then passes on a clean retry was slow, not stuck - a transient slowdown, not a real hang.

## What makes a failure safely retryable

Automatic retry is only correct for failures that are genuinely transient. Retrying a deterministic failure wastes minutes and hides a real defect, so the classification matters more than the retry mechanism.

- Safe to retry: network timeouts, registry 5xx, transient DNS failures, a service container that was not ready, a spot instance reclaimed mid-run.
- Not safe to retry: assertion failures, compile errors, lint violations, anything that fails identically on every attempt.
- Ambiguous, and worth investigating rather than retrying: out-of-memory kills, disk exhaustion, and flaky tests. These repeat under load and a retry only hides the trend.
- Always record that a retry happened. A pipeline that silently retries is a pipeline whose real failure rate you do not know.

## FAQ

### What causes Self-Healing CI: Auto-Retrying a transiently Timed-Out step?

A step is cancelled for exceeding its timeout, but the very next run completes well within the limit. Nothing changed in the code; a transient slowdown (a slow download, a busy dependency, a cold cache) pushed that one run over the edge. A human re-runs the job and it passes.

### How do I fix Self-Healing CI: Auto-Retrying a transiently Timed-Out step manually?

[object Object]

### Can Self-Healing CI: Auto-Retrying a transiently Timed-Out step be fixed automatically?

A transient timeout is distinguishable from a genuine hang by whether a retry completes in budget, so the safe response is a bounded retry. A self-healing CI pipeline retries a step that timed out transiently, and surfaces it only if it times out repeatedly - which is the real signal of a deadlock or runaway loop rather than a slow
