This is a count of completed jobs that generic queues are still retaining rather than purging, typically because the job was submitted with an option to keep it visible for review after completion. Since generic queues just route work, a retained count here reflects historical entries kept for auditing or troubleshooting rather than jobs still in flight. An administrator investigating why a routed job never printed could check sQueGenericRetained to find and review the finished job record still held in the queue.
