Prevent duplicate Frappe background jobs by assigning a unique job_id to frappe.enqueue and checking is_job_enqueued before queueing. This deduplication behavior ensures user-triggered tasks do not overlap or break production reliability across v14-v16.

Frappe scheduled tasks silently fail when hooks.py scheduler_events configuration is incorrect or bench migrate is skipped after changes. Ensure you select the right scheduler event type and run bench migrate to register the job properly.

Handle long-running Frappe tasks by enqueueing them to the long or *_long queue with explicit timeouts. For extensive processing, implement job chunking and self-chaining to prevent timeouts and maintain production safety.

Monitor Frappe scheduled jobs using the Scheduled Job Log and RQ Dashboard. Implementing health and alert monitoring alongside per-record try-except error logging allows you to track background task execution and catch failures quickly.

Safely process records in a Frappe background job by wrapping individual record processing in per-record try-except blocks. Batch your database commits to ensure data availability and isolate failures without breaking the entire job queue.
