A CPU_PINNED line at 0 while the engines report hicache backups means the tier stream is not reaching the router. Both the busiest and the quietest replica are plotted: every replica receives the full stream, so a quietest-replica line at 0 while the busiest is healthy means one replica has lost its subscription and is routing blind.",
