If you drop a Streams propagation when there is queue spill on the capture site, you may experience 2 different problems related to queue spillage that can both be present or exist separately.
The first is related to queue spill for LCRs associated with the propagation that just has been dropped. The clean up process may leave orphan LCRs spilled onto the the spillover queue table (always less than 32) for the dropped propagation.
The second is related to queue spill for LCRs associated with any surviving propagation schedules using the same source queue for which a propagation has been dropped. In this case, you may observe that the queue spill for the surviving site grows constantly.
