It surprises me you didn't get this one. I got it in 6 seconds:
max threads set to 2
hash table memory = 192M bytes.
pawn hash table memory = 40M bytes.
EGTB cache memory = 32M bytes.
6 piece tablebase files found
26330kb of RAM used for TB indices and decompression tables
choose from 2 best moves.
Crafty v18.12 (2 cpus)
