This value counts jobs sitting in generic queues that have been placed on hold and will not be dispatched to an execution queue until released. Because a generic queue only forwards jobs onward, a growing holding count means operators are deliberately withholding work from being routed to printers, batch servers, or other queues. For instance, if a system manager holds all jobs in a generic queue during a printer swap, this counter reflects exactly how many submissions are stuck waiting for the release.
