I will definitely switch to a 64 arch. I installed djbdns on an opteron 
machine and neither i had to use any special compilation flags, or did i 
get any type of unresponsiveness when the service was running with that 
2.9GB cdb file.

Basically it gets down to:

Use 64bit arch if you want to use cdb files larger than 2G.

Thank you all for the input,
