> {{BPServiceActor#pendingReceivedRequests}} is not tracked correctly for multiple storages. Previously this counter was treated more like a flag, i.e. we only cared whether it was zero or not. With multiple storages we need to be more precise in tracking this value to correctly determine when to generate incremental block reports.
