Re: [rules-users] Trapping runaway rules

My project involves rule creation by customers, business analysts, and developers. We have a base set of rules that fire for every transaction and then we fire custom rules within a stateful session. An issue I've started to run into is rules being created that fire endlessly. I initialize the session with an event listener that we use to extract all rules fired for each line item of a transaction. Once the session is initialized and all rules from various agenda groups loaded we do a fireall rules. My questions are: 1) how can I detect I have a runaway rule/rules. Is there a method or listener that could detect this for me? Does anyone have a formula they use to do so? I had thought that I could use my event listener that I track the rules with to grab the last X number of rules fires and see if rule y gets fired more that z times. But is there a simpler method?

2) once I've detected a runaway rule, how can I gracefully stop drools rule execution? I read of the command drools.halt in different posts, but not sure if this would be what I'm looking at doing.

Any thoughts are appreciated. Thank you!
