Re: [rules-users] Significant memory degradation in high transaction system

Yes, we have a YourKit license. If I watch certain objects like the StateFulSession I can see one created for each web session and deleted each time the session expires. I've run thousands of transactions through my dev server in an all night test. The morning results after all sessions had expired showed little difference from my starting point and nothing significant in the rules related objects. We also have a JMX-based free-memory logger in our production environment. The release that introduced the rule engine in a minimal capacity shows some memory degradation as well as much higher volatility and a much greater 'swing' when the garbage collector runs. This indicates to me that something is generating a LOT of temporary objects that are all collected at the next GC run. It would be nice to get a confirmation that we have implemented this correctly. Also I wanted to know of any other connections between a StatefulSession or the objects added to working memory and the RuleBase. My concern is that data might be held longer than it should be (ie: data created in on session is held onto after that session expires) but eventually does get collected - at least by the time all sessions expire. Thanks for your help! sburrows
