Scheduler heartbeat stale

CriticalSCHAffects operatorsRetry: not retryable
The scheduler runner is reachable but has not reported a recent heartbeat. Jobs may be stuck; restart the runner if the condition persists.

Likely causes

  • The background job runner is registered but has not reported a heartbeat recently.
  • The runner process is hung or overloaded.

How to resolve

  1. 1

    This is a platform-side condition. BizKitHub operations are alerted automatically.

  2. 2

    Delayed background jobs continue once the runner recovers or is restarted.

  3. 3

    Contact [email protected] if jobs remain stuck.
