PKID Discretization with KDD99 %10trainig dataset doesn`t work with HNB Classifiction

Hi All,

I`m working on Intrusion Detection Systems and spent much time on KDD 99 Dataset naturally.

But when I tried below combinations:

Discretization & Feature Selection & Classification

PKID+CFS+HNB
PKID+ReplaceMissingValue+CFS+HNB
PKID+CONS+HNB
PKID+INT+HNB


WEKA bird stops almost 5-10 seconds later.

What could be the problem?

Any feedback appreciated..
