Chris,

The hash table is too big for an eng-eng match, don't forget the opponent has
its own hash table too, together they exceed your physical RAM, I am assuming
you have 512Mb.

There is no need, just make sure the 2 hash table sizes don't exceed your
physical RAM minus 100 Mb. In your case put Pro Deo back to 200 Mb.

Good luck,
