A5Poison messages and dead-letter queues

The problem

1 s on screen = 100 ms

One job always fails. Why does every job behind it stop?

One bad job holds the line

The queue hands out one job at a time, in order, and hands a job out again until it's acked.

A5Poison messages and dead-letter queues

A job that always fails gets retried forever and blocks the jobs behind it.
