We have enhanced the storage request processing for distributed threads to avoid a bottleneck condition that can occur in the DDF communication buffer storage. 04E abends due to virtual storage constraints could be seen in V9 and V10 in some customer environments. This APAR has been marked HIPER, but can also improve the current DDF processing when a rush of distributed threads enter the system at the same time.
