I'm working with some one else on tracking down this brain-puzzling 
problem that some people are having with Spade's adapt and adapt3 
modes.  For now, you can use adapt2 or use a static anomaly 
threshold, or not run Spade.  With luck, I can get it figured out 
this week and release a new version.

But first I need to get a journal submission of the SPICE paper off 
since that is due today (a follow up to the ACM CCS IDS workshop in 
Athens).  And get a new SnortSnarf version out (no more warnings for 
ICMP packets and snort 1.7).
