Hello,
In reply to the topic "KnightX 2.5 bug" on a forum:
Yes, the 2.5 version use twice the memory wanted when you set the hash table size in the config file.
This is because this version now use a cluster of two positions for each hash table entry (was one before).
This will be fixed in the next version (soon). For the moment, set the number of bits you want minus one, or set the size in the winboard gui which have precedence over the config file.
I cannot register in the forum concerned, so I cannot reply directly.
