Re: [rules-users] Drools error log msg?

The "after 20 facts or so" makes me think that some constraint behaves differently when jitted (constraints are jitted lazily, to go from interpreted to compiled mode, only when they are used often enough). In fact, there was a bug that was fixed a few days ago regarding a different behavior of "contains". The interpreted version would work as String.contains, while the compiled version would work as Collection.contains - or vice versa, I don't remember right now. Unfortunately, the fix can't be backported to 5.5.0.Final. Can you try to rewrite constraints like : _name:catalog['name'] not contains 'Timer' into _name:catalog['name'], ! ((String) catalog['name']).contains( 'Timer' ) and see if the situation improves? On a totally unrelated topic... I have also noticed that you have a very peculiar data model.. we developed traits in 5.6 and 6.x to deal with relational models like yours.. would you be interested in doing some research and see if/how they impact performance and rule authoring?

Some more details here: I work on an Event Correlation & Analysis OSS solution that's based on Grails & Drools 5.5.0-Final. I'm using a stateful knowledge session and only call dispose() when the app is stopped - but all facts are retracted. The functional testing works fine but as I've mentioned it before when I run the integration testing it fails, because rules are not fired ('ClearAlertRule' is not fired) when I insert more than 20 facts. I saw the errors in the drools log but I didn't know if they were relevant for my problem here. I've attached two picts which document the right and the wrong behavior of the rule processing - also I've listed the rules of my rulebase. Has anybody an idea?
