Research direction
Start by reproducing the failure through the tiflash cli while the tiup bench tpcc run command is active, using the reported tpcc.order_line schema and query. Trace the CLI/server handling of the reported “Unknown packet 101” response. Done means the query completes successfully while the benchmark is running.
