Hi, this error might occur when memory allocation is insufficient. Could you please check if the machine has enough memory space?

Additionally, you can try starting your compiled TiFlash binary using tiup to see if it can start normally with standard configuration parameters, for example:

tiup playground v6.1.0 --tiflash.binpath $TIFLASH_BUILD_DIR/dbms/src/Server/tiflash
