Check the max tries setting for any queue software before putting it into production. With Laravel, its default was infinity. When we had a buggy job, the maximum retries eventually caused 2nd order errors in the (database backed) queue system, such as SQL errors like "number too big" for number_retries column.

I could imagine other situations where infinite retries could have consumed costly external APIs, or - worse - bombarded someone with emails.


Always set converative max number of retries for jobs on a queue.
