IAM role rotation leaves one batch worker using stale credentials

Most services refresh correctly, but one worker process keeps using cached credentials and starts failing scheduled jobs.

Scenario

Most services refresh correctly, but one worker process keeps using cached credentials and starts failing scheduled jobs.

What to check first
  • Identify the primary failure signal in the IAM scenario.
  • Separate visible symptoms from the underlying technical dependency.
  • Describe the safest recovery path and the follow-up prevention work.
Checking checklist
  1. Summarize the current impact and the last known change.
  2. Collect direct evidence from logs, runtime state, and configuration before changing anything.
  3. Separate immediate recovery from permanent prevention work.
Recovery and prevention

Choose the smallest safe recovery action first, then record the prevention work that reduces repeat incidents.

Questions worth viewing together
What is the common failure point after IAM rotation?

One long-lived worker or cache path often keeps using the old credential even after the main service path is updated.
