SCHED_ChainWatchdog

Class · Group: Async

global inherited sharing class SCHED_ChainWatchdog extends SCHED_Base

Extends: SCHED_Base

A scheduled job that finds async chains stuck with no recent activity and marks them Stalled, firing each chain's persisted onError notification once per stall. A chain goes silently stuck when the platform stops its next piece of work without ever calling back — this job is the safety net that surfaces such chains for recovery instead of leaving them Running forever. Configurable via attributes: how long a chain may sit idle before it counts as stale, and how many chains one sweep inspects.

Example

SCHED_ChainWatchdog job = new SCHED_ChainWatchdog();
DTO_NameValues attributes = new DTO_NameValues();
attributes.add('StaleThresholdMinutes', '30');
attributes.add('BatchSize', '50');
job.setParameterValues(attributes);
System.schedule('Chain Watchdog', '0 0 * * * ?', job);
