You will get Debug and fix your failing Celery Redis background jobs
Project details
A task goes into the queue and never comes out. No error, no result, nothing in the logs. You've already read the Celery docs and asked an AI — you got five plausible causes and no way to tell which one is yours.
That's the gap I close. I trace it against your actual code, your broker state, and your worker logs, and tell you which of the five it actually is.
Common causes I find: acknowledgement mode losing messages when a worker dies mid-task, prefetch settings starving workers while the queue grows, exceptions caught and swallowed before the retry ever fires, and result backends silently dropping state.
Starter is diagnosis only — a written root-cause report with the evidence behind it, no code changes. Standard applies the fix with a sane retry and backoff policy. Advanced adds a dead-letter queue so exhausted jobs land somewhere you can inspect and replay, plus queue-depth metrics so you see a backlog before your users do.
I've built this exact reliability layer into my own async inference backend: batching, DLQ, circuit breaker, and Prometheus metrics under load testing.
