From 876fdc1c90a885a58644c8757bc1283c9fd5bcb7 Mon Sep 17 00:00:00 2001 From: Vasilis Liaskovitis Date: Wed, 1 Mar 2023 13:46:28 +0100 Subject: [PATCH] cups/http-addr.c: Set listen backlog size to INT_MAX (fixes #308) Use a listen queue size of INT_MAX, which should default to the maximum supported queue size on the system. This avoids the problem of the listening backlog queue getting full when there are too many requests at the same time. The problem was observed with the previous backlog size (128) by customers when submitting large batches of print jobs, resulting in some jobs getting lost.
