James, I believe this was related to Drools 2. What exactly is your problem? []s Edson 2009/8/14 James Owen <jco2009(a)att.net&gt; Greetings: Just wondering if this link still applies.

No, I don't think that would be the problem. Considering that we always calculate the full cross products/matchings, maybe that is due to a different implementation of the conflict resolution strategy (assuming the rules are all correct)? Did you checked the number of canceled activations?

[]s Edson 2009/8/14 James Owen <jco2009(a)att.net <mailto:jco2009@att.net>> Edson: When I run WaltzDB-16 I get only 9K+ rules fired rather than the "normal" 21K+ rules fired. I'm thinking that IF this logic still applies THEN that might explain why WaltzDB-16 does not fire the requisite number of rules.
