Description of problem:
cupsd may drop requests if many requests come at one time, because listen() backlog queue gets full. This may lead to losing print job requests etc.

Version-Release number of selected component (if applicable):
cups-2.3.3op2-18.el9

How reproducible:
Sometimes during heavy load of requests to cupsd

Steps to Reproduce:
1. send many print jobs to cupsd in short time
2. check if some of them are not processed

Actual results:
In case backlog queue got full, some jobs might not be created

Expected results:
All or at least more jobs are created
