Fixed an issue where the paths between the control plane and the dataplanes in network processing cards (NPCs) stalled in the dataplane-to-control plane direction due to the Ring Descriptor entries becoming out of sync on each side. This produced unrecoverable data path monitoring failures, which caused the chassis to become nonfunctional.
